The big problem with Reddit was that the moderators abused their power to censor. (and in some cases, moderation was infiltrated with bad-actors, trying to create a controversy to manipulate a group of Reddit users to get them to leave).

The problem with Reddit alternatives like Voat; was that there were no responsible moderators who would censor the absolutely indefensible.

In other words: Welcome to the same problem the Internet has known since use-net. Hell. Since the BBS days.
