Do we need a thread in meta for this? This seams like a great thing to have either followed the advice above of:
this is a reputation topic.
Yes it was and usually I use to post this on this topic
[User Generated Mk III] - Known alts of anyone Mk III and I use to report them and point the link of my reply on that topic. You can report it as well, there's nothing wrong with it I guess as to the mods will look into the report.
We need to be better at keeping things clean ourselves if we are going around trying to clean up the forum. All it takes sometimes is the report to Mod function or posting in an established thread if you want like minded people to pull at the strings as well. Also giving you a chance to link to a post explaining your "report". If your information is sound the accounts will receive a ban from the powers that be.
