I downloaded my entire reddit activity and have been going through it slowly, changing all my comments to links back to themselves. Today I got this:
Hello, You have been permanently banned from participating in r/funny because you broke this community's rules. You won't be able to post or comment, but you can still view and subscribe to it.
If you have a question regarding your ban, you can contact the moderator team by replying to this message.
Reminder from the Reddit staff: If you use another account to circumvent this subreddit ban, that will be considered a violation of the Content Policy and can result in your account being suspended from the site as a whole.
Did you know flamethrowers are actually legal in 47 out of the 50 states, last I checked anyways? They're considered as work tools to melt tar for roofing and road work and such.
But yes, any which way you spin it, it's a really stupid reason to get banned.
