There is a kind of spambot that I call a Sleeper. It poses as a legitimate account by “stealing” arbitrary tweets from the public timeline and tweeting them as its own. As it follows people, a proportion will follow back. Eventually this account will have built a mature following and can “wake up”. i.e. it can start tweeting its cargo and even send DMs.
These bots are usually easy to spot because their tweets all show as being “From API”, meaning that the update wasn’t sent by a registered app using OAuth. If I was a spammer, I’d be wanting to fix that because it’s a dead give away. I’ve also seen other services such as HelloTxt being used by these bots, but just now I spotted something new. – Tweets from Tweetie.

I made a major change to TwitBlock the other night. The change was made to protect people who are heavily blocked, but are not “spam”. Of course that depends on your definition. (A topic for another day)
Originally each block on account would yield 10 points. Then I became aware of just how murky this issue is. Barack Obama is blocked by many accounts (Republicans no doubt) plus some people with extreme right wing views were being blocked heavily. Then the complaints started. People whose businesses survive on a huge Twitter following accused me of destroying their reputations, and generating further blocks on their account by showing the number of existing blocks.
So now two things have changed for the time being:
1. Clicks on “not spam” are deducted from blocks;
2. Blocks are diluted by the size of a user’s following. 10 points are added for every 1%. So, if you’re blocked by 40 people, but are followed by 8,000 this will only yield 5 points.
Although this has stemmed the complaints, the scanner is less aggressive and lots of real spam accounts are not showing up with high enough scores. I am struggling to find the balance in the face of all of this and may have to tweak it again.
I just received an email that I thought would be of interest to everyone. I have removed people’s names for reasons of privacy, but I have left the spelling mistakes in for a sense of realism. My open reply to the author follows at the bottom. Read more…
Constructive criticism of TwitBlock seems to have quite rapidly turned into some quite aggressive complaints including several demands for immediate closure. This is not intended to be a malicious project, but with a sudden rush of large numbers, I am experiencing a minefield of issues that I did not predict. I am doing my best to fight these fires, but please bear a few things in mind a few things when feeding back to me:
First and foremost, this is alpha software.
I did not expect 7,000 visits a day after just three weeks. (I can thank Mashable for that overhead). I am constantly thinking of ways I can please everyone and still keep the application doing what it needs to do, which is help people remove illegitimate followers.
