As long as zaps are anonymous, the bots can do it to their heart's content, and I won't know (or care, because as you note, money is money). It's crappy interactions I'd be more concerned about (and I'd mute them harshly, which I also did on Twitter back when it was a thing).

If it came out after the fact that, say, 20 sats on every zapped post of mine came from a bot, I don't think it would bother me much; but if I found out that literally 75% of my sats here came from bot activity, it would feel a little depressing. The sats are nice, of course, but I also just enjoy having my ego boosted, and that would be a blow.
