I know it's not what's going on in this thread but man this was a pretty common scam on reddit for the last few years I was on it (so it's probably still happening over there). OP would post a shirt or mug or whatever related to a sub and someone in the comments would ask where to get it, then another account would come in with a link (sometimes to like amazon, sometimes to a sketchy or dropship site).

Cool when it happens for real like here, but I'll be sad when lemmy gets big enough to attract those accounts.

I saw an ad for it, I guess big data knows I'm a queer nerd.

Responding for link also

Sadly, I don’t. A friend sent me this in a text, and he also doesn’t know where to buy it.
