I use to have a profile of Seek Arrangement but all contacts were fake.
They all talk the talk, but always mention something like they have 5 kids, or something to let you cancel the chat with them. They normally through a comment like that after a couple of message exchange. That way, it is you that cancel and not them. I normally play along and say something like 5 kids is not issue for me, always polite and calm even if they try to start an argument. At the end, they cancel the connection and delete the profile.
If you block them, then the profile stay and they can use the profile on someone else. If they delete they have to create a new account, upload photos, so wasting some of their time.
All part of the fun and games
