P.S. The way you can self promote while staying within the rules is to sincerely become an active member of each community after which a small amount of posts can be part of your own content. This also deters cross posting your own content across several subs at the same time which tends to annoy people who see your content repeatedly. If you do this, you can still end up in hot water because people reflexively hate self-promotion, but you're a lot lot less likely to get banned. The thing is that people with no investment in the communities they're posting their content into will not do this, which is precisely the point, Reddit wants the regulars of that community to post content not drive-by self promoters. This overall ensures quality in a fair way. It doesn't work that well, Reddit has been astroturfed for eons, but it works somewhat.

The rules of reddit apply globally in communities large and small, a moderator might like you and not ban you and maybe users on a certain community like you and don't report you, but if you break the rules of reddit yeah it's fair for you to get banned at any time by anybody with the power to do so with them citing that rule.
