They enable bad actors because

- they can be faked (scammers on youtube and twitter rely on bought likes and follows to make them appear legitimate)

- they distract people from plain LN, which has none of the drawbacks of zaps but can send / receive value just as well. Newbies now come to see zaps as the "de facto" way of sending / receiving sats. A bad actor who wishes to hinder LN adoption would encourage zaps, because once new adopters see that scams are very possible with zaps, once they see "sats" can be printed out of thin air, they will conclude there is no difference between bitcoin and shitcoins.
