It's strange you would Post this Question @Frank_Woods. Just Yesterday, some rude and crude and "Needing his mouth washed out with soap and water," put some horrendous bad language on my own Comment, along with doing this to some others. I turned him in, after letting him have it, to a mod friend of mine, and he was banned from That Question and his ascine answers went with him. I do not mind if someone wants to comment on my own box but be diplomatic, not snotty in a such way where I have to reprimand them, especially because their own Comment box is being offered to them. Yes, wouldn't it be nice if there was such an "Approval comment" Button... Might make the mods job, as well as the Administrator's job, a little easier and us here, dear, on GAG... A bit Happier. Good luck and Good Point. xx
Sometimes I think that would be a nice feature due to the large amount of trolling going on lately but then again, if that sort of thing was implemented, that would only make this site even more filtered and over-regulated. People who are legitimately just expressing their own opinions would start doing so even less so I think I'd prefer to just take the good with the bad.
There are many features that can help minimize trolls like no anonymous posts allowed, permitting responses from just one gender, etc., so those types of options should suffice.
