At least two mods, /u/theskynet and /u/davidreiss666, have been caught removing multiple articles. This example consists of articles about muslim immigrants killing christian immigrants on a boat on the way to Italy.
At first, an article was removed, and no explanation was given. A new article was posted, and immediately removed. And again. And again. One time a bogus reason was given.
This comment giving an overview of the deleted threads was, of course, swiftly removed. People who still had the links to the deleted threads were discussing the censorship in these, but their comments were quickly removed. You really had to be there to witness the shitstorm, thread after thread after thread was deleted and people being banned. I personally messaged the mods, but received a spectacularly childish answer (The image u/theskynet responded with is this one: https://i.imgur.com/yGC5Iht.gif.
Only after outcry a megathread was created by other mods. The comments are almost all about the censorship instead of the article. Interesting comment chain, but be sure to scroll through the other comment chains and notice how many were deleted.
And then something new came to light: turns out there is a rule that automatically deletes every comment referencing davidreiss666, to prevent people from discussing his actions. Be sure to read the first quote in the comment, another hint at how much censorship is going on.
And then it turned out that /u/davidreiss666 had already been removed from /r/Canada for similar reasons. See this and especially this.
So, people tried getting the same thing done on /r/europe and made multiple petitions and referenda to remove the responsible mods. Multiple, because the first one was quickly removed. And the one after that. And the one after that. You can see how many upvotes they gathered in the mere minutes before they were removed.
No reason was given for these removals, no statement was made
It does seem that not all /r/europe mods approve of this, after I messaged them in private. I got this response. But it appears they do not wish to speak up.
And then... nothing. People forgot. To my knowledge, nothing new had happened to remove these mods. In all likelyhood, censorship still continues on a daily basis on /r/europe. Those here that still frequent /r/europe, consider all this before your next visit.
