That looks like Grindr which is not for hiring providers. It’s against their policy and someone caught can get banned.
I see providers I find somewhere like a Rentmen. I look for dates / whatever you want to call it on Grindr. I don’t look for dates on Rentmen and I don’t look for providers on Grindr. Nothing wrong IMHO with what the person in that post has said as it’s very annoying to think you’re speaking w someone about a date (no $ involved) and it then turns into something else and it happens very frequently. How would a provider feel is someone hit them up on Rentmen and said “I love your look, but let’s just go on a regular date or hookup, and I won’t pay you anything”?
Why is this person’s post offensive? He is not saying “I hate providers”. He is saying don’t contact me if you’re a provider looking to be paid from meeting me. Grindr is also full of opportunists looking for a one off paid interaction even if they’re not technically providers ongoing, and maybe he means that too.
