I would like for users to use their main account to attack someone, but as others have stated in other threads, people use alts to avoid backlash or political bs from happening. It's not illegal.

As far as tagging their alt account, I think it's respectable for someone to put a note in the form of a neutral tag letting the forum know their alt account. Nothing wrong there either.

If you are going to try to throw some shit on the wall and see what sticks, you m ight find some stickier shit cause this ain't doing anything but sliding off the wall.
