Huh, this is the third identical reply from 'kjs3' to 3 different comments on very different posts, with no seeming connection.

Surprisingly, I only noticed this 9 days later, it must have been overlooked several times.

I had thought the account got hacked but since the recent submission history seems to be of a person, this is likely a weird attempt at low-effort trolling?

Bizarre, and I don't even know who 'kjs3' is!
