I’d ignore them. I know that’s easier said than done, but the person’s bio is “It’s just a test”. I’m assuming they’re the type of person to comment to get a reaction. They even said you haven’t commented a positive thing on a single post which it in itself is a lie.

Ignore them because they clearly don’t know what they’re talking about and it seems like just another negative person trying to ruin your day. You have people who care about you and focus on them rather than people like that <3
