An update to the subreddit rules

Hey survivors!

Today we had a discussion internally and decided to ammend Rule 2 of the subreddit, so its description matches the spirit in which it's enforced.

Previously, the rule stated that player names, usernames etc must be blurred/obscured. This requirement has been lifted. The rule is really intended to prohibit individual or group-based insults. So, now, users are free to post any screenshots and videos without needing to edit them further.
