I have a friend who was a member of this subreddit, for some time.. He made the mistake of going onto another subreddit and commented. Those comments were deemed bad but they were especially bad because it was from a link from a post.. This is apparently a no-no.. I wonder, now that I've joined whether or not I can comment on other subreddits, be it not from a link from a post from this subreddit? Let's say I have difference of opinions, may that be deemed an issue to this subreddit up to an extent where I must be sacrifice to "save face"?
