I have a profile. The profile has an email address and password associated with it. No one (that I know of) can post as me, and I can't post (or pose) as someone else. Somehow, somewhere, we have ALL created an account with a password. I'm suggesting that you put something in place during the account (or profile, if you will) creation process that weeds out the robots, spammers, and ne'er-do-wells. I know this software is super old (2012, right?), so if the answer is "it can't be done", then we all just need to deal with the spammers as they come along until you or someone else comes up with a better chat room/forum to participate in that DOES have modern (ie, post 2013) technology to keep the baddies out.
