There are accounts like this across the For_Bodies universe. Some are better than others. Problem is no one looks at post history.
If the same account is asking the same questions periodically over a decade then it's a damn fake.
You can even set them up when they ask for parts. These fakes will desperately ask for parts, some of it stupid easy to find, and then when you provide it they never buy; proving they're time wasters. Then they'll magically put stuff up for sale and say it's sold to get people to think they actually are reliable.
Then they sucker people on fake ads then disappear
Some of these fakes use the same username on car forum after car forum. If you see an account making the same stupid posts but just switching the brand then that's a red flag
