fair enough.
This post will be updated as fake accounts are received. For those questioning the information here, we place accounts here that a) post multiple comments of the same sort (i.e. Spam) and b) accounts that are obviosuly trying to entrap twitter users who are tweeting from Iran or c) those who obviously are trying to spread mis-information. If we arent 100% sure we will put in it the “To watch” or “Suspected” list.
i admit there's ambiguity there with (b) and (c), and clearly i am assuming there are processes going on they're not putting out (they being the people compiling these lists) in the PD, so to an extent if i make any complimentary remark in their direction it's on faith

which doesn't answer your question. i got myself a Twitter and that FindTheRats that Vim linked to seems to show their working a bit.
eg one recent tweet appeared to reprimand another user by saying they didn't see information or mis-use, just a different pov to the situation. another tweet cautions "We're not silencing different povs, just trolls and spammers spreading misinformation." (you'd have to be following the twitter in question to get a broader overview and frankly i know you don't have time or inclination for that when there are people marching and heads in danger of being cracked.)
i agree about the well-intentioned SF techie example.
am sure a lot of people putting up proxy servers might not have been able to find Iran on a map two weeks ago and in helping creating space they are doing something helpful.
but that excellent article Vim linked to about just war theory's place in assessing the morality of DDOS attacks (
wonderful piece that Vim, BTW, ta) shows up just the sorts of points you raise; i'm with you in the ambiguity camp in that sense.
