That's the first thing that came to my mind, but unless there's solid proof I would personally refrain from making accusations against him.  And when inactive accounts start applying for signature campaigns, you pretty much know they're alts of somebody.  That doesn't necessarily mean they're going to be shitposters, because there are good posters here who have multiple accounts, some of which we likely don't even know about.

OP, what's your motivation with this thread?  Did you not get accepted or something?  Because I don't see this as any great injustice, not to the forum and not to the applicants.  Having said that, if it were shown that Murat has a relationship to any of the accepted members' accounts, that would be different.  Until then it's kind of a non-issue.

I haven't looked at any of the applicants' posts, but if what you say is true then he might suck as a campaign manager--but I would still maintain that no injustice has been done to anyone.  This wouldn't be the first time a campaign manager has chosen shitposters for his campaign.
