Lemmy has an option to mark an account as a bot under user settings, OP had a bot icon next to their username on all of their posts with a message that said the account was a bot. They have since disabled that setting for their account, so it no longer shows up, but you can see how someone could have jumped to the conclusion that the account was a bot (this icon won't show up on all Lemmy UIs, it's missing from the mobile website/Jerboa app, but it's shown on desktop). Anyway, no need to use such incendiary language, you may not be angry but it can easily come off as that over text.
