I've been talking to a guy who has a similar background as me ever since I was offered a job at the same place of work. He's been really helpful in offering to look at apartments in person for me and checking in to see how I'm doing. A few friends of mine happen to know him and had positive things to say about him that made me curious and interested in getting to know him more. Then I stumbled across his personal instagram account, which should be private. FFS, he had one post where he bought a piece of art fetishizing lesbians making out and linking the page he has been a longtime fan of, which has tons of porn-inspired artwork on there. That made me look at the list of accounts he's following and oh hell noooooooo - he's got OnlyFans pages and Belle Delphine along with other nearly-pornographic pages. Forget it. I am aborting this mission, but will remain a friendly colleague.
Note that 99% of his instagram posts were fine, so if I hadn't scrolled enough to find that one that tipped me off, I may have forgotten to check what pages he's following. Going forward, I'm always checking the pages they're following on instagram.
