@InfiniteSnowflakes Not any more, they evacuated this room and are now nicely playing in the bot room

Infinite Snowflakes

ok :D

nicael

@hichris123 It is, because can be abused. Nobody wants to fix it, so I can still use this power legally. e.g. meta.patents.stackexchange.com/posts/226/revisions

hichris123

@nicael "so I can still use this power legally" - no, and that's grounds for suspension. You don't go to the police and say "This should be illegal"... and then go right out and do it.

@hichris123 But mine can cause the serious abuse.

ProgramFOX

4:56 PM

@nicael If someone abuses it, the mods can simply ban that person.

hichris123

@nicael It's a very edge case.

It has to be a question that previously had a [status-*] tag.

And it has to be a suggested edit, right?

You can only suggest edits to posts on mSE.

Infinite Snowflakes

And reviewers can get suspended as well for approving it

nicael

@ProgramFOX So why the hell wasn't I banned yet??!??!???!???!???!???!??!?!!!!?!??!?!!???!?!?!??!?!?!??!?!?!??!??!?!??!?!?!?!‌????!??!?!

@hichris123 Oh no, let me do it myself :D

hichris123

4:58 PM

@nicael Okay, how many questions have had a [featured] tag at once? Probably less than 1000?

ProgramFOX

@nicael I don't know, but probably because you reported it and didn't abuse it further.
