I got one of those spammy FELT comments. It looks like part of the Aquarius Academy spam project. The titular account tends to comment on many, many posts long past payout with vaguely inspirational quotes which appear to be generated from a generic list, since they often repeat. Bots are a plague and should be downvoted on sight IMHO, with exceptions for real established community curation projects.
