Tinder profile? Cheating?

My friend is on tinder as she is single and looking. She randomly messaged me saying “get yah boy off tinder” I asked her if it was the profile with his picture turned sideways (as another one of my friends saw the same one about a year ago) she said yes. When w different friend saw this same profile about a year ago he told me his ex had probably made a fake one (as she is psycho enough to do so I can confirm) and pointed out that the age on the profile wasn’t even correct which it wasn’t. His ex messaged me as well a little over 6 months ago with the same profile claiming he’s cheating because she saw this. Weird thing is not sure why she’s on tinder when she’s also in a relationship so i kind of do believe him when he says it’s her making one up.... wha do you guys think and I thought tinder only showed profile that were active the last 7 days ? Does anyone know?
