I definitely take into account how someone acts on a forum when I'm to do a purchase (though most I've bought from aren't active on any forums). For example there's a breeder pretty local to me that has pretty good feedback overall but I've seen how he and people close to him acted in certain BOI threads and I wouldn't work with him if he was the last breeder on earth. They acted totally unprofessional and acted down right disrespectful and childish. So yep, I take that into account.
