not on here. that's why lemmy (and most other decentralised platforms) is so good. but on some other platforms ppl sell their likes farmed accounts to marketers, so they can use it to push their viral campaigns. those platforms usually favor accounts that get many likes and the posts they make somehow with the algo or by auto enforced rules. for exampke minimum karma required to post in some reddit communities etc.. marketers can take advantage of that if they get ahold of a suitable account. that's why some ppl repost and ragebait like mad on those platforms.
