it's possible they aren't tagging out enough.

i think i play a reasonably popular character tbh and am an ok writer tbh? all the same i often don't get tags back when i tag out on memes. there's a balance, you have to tag out knowing not everybody will reply. but because i fear having more tags than i can cope with at first i would put out only two or three tag outs and it was easy to not get tags back

everyone is doing this, that's probably a lot of why meme tags don't get tagged back. that and we all suck ofc. just tag again
