It's pretty suspicious that this happened right after you got unbanned. He didn't just happen to stumble upon an image disapproved 5 years ago. He's actively trying to snuff you out.
You'd think that people who do actual work for imgflip would value the 5th most successful/4th most followed user of all time, but instead he treats you like trash for no reason. imgflip is dying for a reason. He has the worst sitemod reputation for a reason.
