I spend a lot of time thinking about Spam. It may be an inherent danger of being a Programmer. Even though I take care of my email address not being posted around the internet I get junk mail. Some of it is quite funny, although I hear some people fall for the bank with unclaimed money in Nigeria… so I guess not for them.

I bet back in the day people said that spam would ruin email, and I don’t mean to negate it as I know spam costs companies a lot in lost time and productivity. But I think Spam on Twitter and Facebook is even more interesting.

Take Facebook. The primary source of spam for me on Facebook is Facebook Applications, that send me notifications inviting me to add things I have no interest in and frankly don’t want accessing my personal information to my profile. I definitely consider those to be spam, and block any that I receive. On the rare occasion that I do consider adding an application, asking me to notify some / all my friends will immediately cause me to change my mind. But – many of my friends who I’ve actively acknowledged a relationship with clearly don’t consider these aps to be Spam, as they add them to their profile.

Maybe this is similar to email. After all, whilst the vast majority of people consider invitations to buy Viagra online, or contact from a bank manager in Nigeria to be spam sufficiently many people respond that it’s worth the cost to the spammer of harvesting email addresses and buying the bandwidth to send the spam out. I think the difference is, I don’t personally know anyone who buys Viagra in response to an email or really believes that they’ll get thousands of pounds out of Nigeria. So the response rate for spam on Facebook is higher? Or one person’s spam is another person’s… ham?

However spam on Facebook doesn’t (thus far) have the power to ruin the whole experience. And since the Facebook applications are now old news, I definitely get fewer notifications. Twitter though – is different.

Twitter has the issues of Facebook and of email. You can get spammed by people you follow (like you can get spammed by people you’re friends with on Facebook – the Spymaster game springs to mind) and you can get spammed by people you don’t. There’s an intereting article on Twitter spam here. But the real way that spam annoys me on Twitter is because it takes over every trending topic. So, in an unscientific study I checked the trending topics a little after 19:00 BST today, and counted how much was people just including the topic to get their post showing up in searches for it.

So there’s an average of 15% spam, which is lower than I expected (clearly things have improved since this article) but still – some trends are as high as 40%. I want to say – really, does anyone fall for this… but clearly like all spam enough people do for it to be worth the very low overhead for spammers to do it. One of the coolest things about Twitter is it’s ability to capture the zeitgeist, and trending topics being full of spam damages this.

Another thing I consider to be spam is pyramid follower schemes. You know the ones, you follow everyone and give them your details and it spams your followers with the link and adds you to the list, so the next idiot follows you. I’ve un-followed two people (doesn’t sound like much, but I only follow about 50-60 people) for using these. I loathe them – and there are so many! I’ve been keeping track of the ones that come up and (these are just those that I’ve made a note of) have a list of 13 since June. They have such inventive names as: “Twitter Train”, “TweeterPro”, “GatherFollowers”, “BestFollowers”, “FollowersFast”, “QuickFollowers”, “ThousandFollowers”, “EasyFollowers”, “FollowersFree”, “AddFollowers”, “MaxFollows” and they all look the same, and all have the “VIP” option – which is how they make money. Really? People pay to spam the followers they have in the hope of getting more followers who are only following them in order to get more followers themselves? Really?!

Great article which highlights the stupidity of such schemes and that the best way to “grow your follower count” is organically, by interacting and treating Twitter as a conversation medium not a broadcast medium is this one. For people wanting to run a live Twitter stream on their website, spam in the search results is a real issue. TidyTweet aims to minimize this (and take out inappropriate language as well). Whilst there have been a plethora of “make money on Google” links lately, even legitimate companies have been guilty of spamming, so I can’t see there being an easy fix. And, when this kind of promotion makes it into the trending topics I wonder where we draw the line between what’s spam and what’s just an aggressive and questionably honest marketing strategy.

Unwanted @ messages are another form of spam that’s pretty common, although Twitter seems to be clamping down. This morning I had a RT that I never tweeted in the first place, but by this afternoon it (and presumably the person who sent it) was gone.

Finally, Bot’s that follow you because of keywords or just because in the hope that you follow them back and click on their links are the things that annoy me most. Apparently it’s grounds for account suspension, however I haven’t noticed much effect on the number of times I get added by accounts following this strategy. I’ll have to write another post just about this, because this one is already too long. Briefly, for the past 2 months I’ve been tracking who follows me, if I suspect they used a keyword, and whether or not I followed them back. Since the start of June, 120 people have followed me. If you check out the number of people I follow, it’s apparent that I haven’t followed a fraction of them back. I’m also not being followed by much over 100 people, so clearly they haven’t kept following me! They often give you 24 hours to follow them back, and then unfollow you in order to maintain their ratio. In fact, 120 is inaccurate because this contains the same account following me 3 times!  Of this 120, 3 I was already following (when they followed me), and I followed 21, 3 of whom I later unfollowed. So 80% of the follower notifications I received I did not consider to be worth following back.  This article demonstrates an extreme example of this. That’s a pretty high rate of spam. If you’ve been following everyone who follows you back, there is something you can use to get rid of them – mashable has a good article on this.

Of course these are just ongoing issues I have with spam on Twitter. There have also been isolated incidents, like when loads of legitimate accounts were hijacked, or fake celebrity re-tweets. Twitter is also definitely trying to minimize the issues of spam, although with mixed results, such as blocking bad URLS, and suspending accounts. But with the rise of sponsored tweets, such as this service it may get more complicated.
