Well they don't really make it to known. You may know that a capital M against anyone's screen name means they are a mod of the particular stream you're in but otherwise no one lists them anywhere that I know.
They quickly pulled the reposted non politcs one I mentioned earlier.
If your memes were de-featured (dis-approved?) then someone has flagged them for whatever reason. The snowflakes have abounded on here for 6 plus months now and they go around flagging memes because it upsets them or their sensibilities. Your words are upsetting to them hahaha.
Personally I'm sure they know it pisses us off and they have nothing more meaningful in their lives to do than chase memes they don't like. I think many are upset that the right leaning memes are King in this stream and they know they can't out do with content so they are trying this. Which ultimately could be successful if you let them win. I know how it feels when this shit repeats and have been at the receiving end for a while now too.
Also the they, who are flagging things may only be a handful of Muppet, 6 or7.
