In either case, lemmy's web interface hides a lot of context by default when answering via the "messages" notifcation. So in a sense, with that one could reply endlessly. Then again, that's not part of our experiment I'd say.
Oh boy... can't promise you that I will last that long.
I know it sounds pathetic, but is replying to one's own comment an option (just for stress testing)?
