This is a bit thin though. Going to need a bit more to go on.
My own comments were immediately deleted as well. It seems the bot automatically removes every comment containing certain words (Epic, EGS etc), while only the positive comments are restored by the mods later.
I'm not sure this is merely overreacting from the mods against the negative vibes towards Epic on that sub, or actually a result of the advertising deal between Epic and Reddit. But it's some China-style censoring nonsense anyway.
