At this point I am afraid even mentioning Lemmy in a couple of subs will lead Reddit in masking you as spammer, I would have taken it easy even if one of the subs I cross-posted to removed it as spam (things were dead silent, and suddenly a full account suspension comes in, not to mention my sub being banned briefly that is also about Lemmy prior to that), so I don't think this is because they actually look at this as spam, but a convenient way to mask me when they actually censored me and my sub that was growing.
