Just now I noticed my previously approved game description has been chopped up by a much more aggressive filter. It picks on all social site names and even player nicknames. If that’s not enough, it completely destroys all spacing and indentations if there’s a single filtered pattern in your text, replacing your nicely formatted description with, caugh, pretty much unreadable garbage.
Now I looked up other game descriptions and I didn’t see the same happen on them, but I bet this has to be triggered by when you change the description or another moderation action has been taken - I noticed this right after my icon got rejected (and approved after I changed a pixel).
