I volunteered at a thrift store years ago, and I was in charge of looking at the condition and prices of books that were donated. One person dropped off about 10 boxes filled to the brim with Playboy cartoons. They weren’t worth anything and couldn’t be put out on the floor anyway, so they were thrown out. I also remember that someone donated a biography of Benjamin Franklin from 1835. The cover was coming apart, but the pages were in wonderful condition. We sent that to a bigger thrift store in the area that ended up auctioning it for about $350.
I wonder if it is fishing itself that they don’t like, or if it is the prevalence of fishing photos on dating sites. I know that a lot of guys post fishing photos on their profiles (probably because most men don’t take many photos of themselves but will take photos with a nice catch), so maybe it just seems unoriginal or low effort. I’m honestly not sure, but my only point is that it may not be the hobby itself.
