Well funny is subjective but i understand why you posted them to lighten the mood and have fun.
You said yesterday and i’ve noticed you used the same drinking meme gif for a year now. Maybe that could be it on why you can’t post memes (assuming you can’t now)? And no, i’m saying it’s vandalism or advertising, i always noticed that the gif is a little… Risque. But i digress.
Not honestly sure why their apparently Vandalism or advertisement.
