All of what Spez said would certainly be worthy if not for the following:

1. Powermods controlling an unusual number of default subs. This is particularly notable in news and country subs, almost entirely given over to left-wing viewpoints.

2. Mods sharing block lists that automatically bans users who have posted in a politically denounced sub - regardless of what they post. This includes subs that appear in /r/all. Although not explicitly against their rules, Reddit advisees against this practice, thus they should at least remove such subs from /r/all. It's bizarre. Even subs as diverse as mental health and hair-related subs, run by SJWs, do this.

3. Shadowbanning, with little explanation as to why this occurred, only becoming apparent if a friendly mod notices it.

4. Shutting down all conversation concerning a paedo admin.

5. Identitarian left subs brigading and spewing terrible vitriol. Meanwhile, subs that don't respect party orthodoxy tread a fine line to avoid being shuttered.
