I havent read all the posts but wtf is this shit

There is no need for mods to be visible, if a member has a problem which needs solving all he needs to do is send a report and the mod will attend to him. Simples.

The invisible feature is handy to catch spammers, people using racist slurs etc. So personally i dont think it should be removed.

Members should know how to follow rules regardless of the online status of an mod. And like i said before a simple report would do the job and a mod will attend to it if a member needs help .
