Hi everyone,

I have one question about detecting duplicate accounts. Some troll accounts.

I mean one real person registered many accounts using web proxies and start posting troll posts and causing trouble in my forum.

These troll account make any polls in my forum meaningless. Also causing any member reviews meaningless too.

Any suggestion to combat these trolls are appreciated.

there really is not any good way to deal with these sorts, except manually handling each account

I just think if the SMF software can put some cookie into login/logout process, even the troll member using proxies, we probably can detect the troll.

Maybe using cookie storing a list of recent login member names in the same browser. This might help establishing the relationship between these accounts, a first red flag before real troll posts coming from these account.

Aside from generating an unnecessary cookie, how would that help?

Does the bad behavior module and the other ones that use the project honeypot method of spam control usually pick up on proxy useage or mis-use and block the user from causing any mischief?

The urge to post troll posts perhaps will lower their guard! They probably will logout and login instantly. ;D

Yes, each account needs to be addressed individually, but with just a few clicks you can effectively shut down their ability to post anything at all using the ban listings functions, depending on how determined a culprit this is will govern how severe the banishment, what i normally do is use a partial ban by taking away their ability to post permanently because a normal troll will make their intentions known with the very first post, so, if you have your usergroups set to make newbies pass verification before being approved to be viewed by the general audience, you will see they never fail to be caught right away and the normal users don't have to see their crap because you remove the post and ban them immediately, its no use using the warnings system unless you have a really busy and active forums site where someone may have just slipped up a little and stepped on a few toes or started a slight ruckus between other users, it happens

Does SMF have anything like XF's Block Proxies, Trust+, DragonByte Security plugins?  The latter two, in particular, are very effective at halting poxy sign-ups.

I have the same problem, and it maybe more annoying with some gmail account that have been banned but they can register again by adding a dot in their email account name. I have no idea to deal with this.

To deal with the Gmail problem requires a rewrite of SMF's ban system.

maybe limit of account per IP ?
the ptoblem is ip can be changed easy =/

Which is why you don't rely on it as it's super easy to get around.
