These are trolls. We're not immune to trolls here on Lemmy. They have a schedule that can be tracked, lol.

• Don't take it personal
• Downvote them
• Leave one or two comments at most setting the record straight
• Find something more interesting to discuss in another comment or thread.
• Don't take it personal or think it's all of Lemmy.

Any online space is going to have these trolls, but especially a space that's kind of bucking the system and can't be as easily controlled.
