[twitter-dev] Re: Anti Spam
Very true and exactly what we plan to do, although when summed up you find that a scoring system is best handled on a server and not a client, i.e. Twitter Search. In the mean time we've got enough things we can do real-time in javascript for our 'filtered' feed. In our case we're dealing with events/trending topics which can have large amounts of data so run-time web app processing time becomes an issue.

[twitter-dev] Re: Anti Spam
We had a chat about Twitter spam yesterday and would like a points based approach to user ranking or spam rating. For those of us working on 3rd party applications, having a spam score to be able to make quick decisions on with regard to searches would be very useful. For example, a new user would have a higher 'spam-rating' than a long time user. Someone with a huge follow:follower ratio similarly. Given how spam is used on Twitter, there are several categories which could be dealt with at run-time on a server but less easily on a live application. BTW I worry that to join the abuse team one has to "have what it takes". Does that mean they hand out large amounts of abuse ?-) On May 18, 7:12 pm, Doug Williams wrote: > We have a team dedicated to controlling the number of spam messages and > accounts in the system.

[twitter-dev] Anti Spam
I'm working as part of the #twumpet team and as part of our project we're developing an application as well as running some Twitter events - the first having been Eurovision earlier today. As we hit the top trend, #twumpet got - and is still getting - enormous amounts of spam. Spammers are signing up, blitzing messages through one immediately after another, and then moving on to the next account. Does anyone know if Twitter are going to stop users firing tweets off one after another so blatently like this? I just checked on a couple of top trends and all I can see is spammers tonight. Also, as a developer working on a project which will be dealing with trending topics and popular searches, I need a quick way to throw out spam messages. I have a couple of ideas for strategies but would be interested in discussing them, and perhaps a group effort which used Twitter itself for rapid short term spam classification & reporting [through Twitter search or a further API]. The one thing about spammers is they appear and disappear extremely quickly so any lists would be very short and 'live', at least for now... @newretro
