Trust me, it IS a real thing, it used to be a big problem years ago and I even spoke to someone at EA who confirmed that it happens, they said that if they find an account that does it regularly that they ban them. There have also been streamers do it live on stream, showing people how to do it.
I think it happens, but I don't think it happens enough to think its a glitch. I think it's usually EA servers.
