Are the men who pay for OnlyFans low IQ?

I have a guy at my job who has been talking about his “model girlfriend” the past month to me and other dudes. He showed us the photos of her and she was a 10/10 IG Model bad af. A lot of us were shocked he had no photos with her at all and we work in a warehouse ik he don’t make more than $60K a year so was shocked how he could bag that. Come to find out this girls onlyfans chat has fooled this nigga into thinking she is dating him and he be paying her thousands and we tried to tell him it’s not even her because she replies fast as hell. He got OD mad at us and we was looking at the other girls in his OF chat thing and they were texting quick af too and he really believed these girls were really talking to him. I found out millions of dudes are falling for this and was curious how these girls make so much money. They be fooling dumb niggas into relationships to pay them thousands.
