Question about bot comments

Hello there !

I’ve got a silly question. I’ve posting sporadically on AO3 since a couple of years and got comments on my last IWTV fic (AMC series + non romance OC). Didn’t expect anything.

Are all « guest » - bots ? One guest has been commenting under every chapter I posted. Not big comments, just stuff like « I loved your chapter, when is the next one ? I can’t wait ! » for example.

Thanks in advance !

(I’ll feel like an idiot for answering these bots if that’s the case lol)
