As you probably know, you can send ‘friend’ requests for recent opponents from within the game. You might also have noticed that the feature doesn’t work for opponents from the fighting pit in Mercenaries.
However, recently I’ve been receiving a couple of requests from a certain character (I don’t see a reason to name them here) each time after or even during a match with them. So far I’ve been wary of accepting such requests, especially if I’m not sure whether they’ve even been sent by a human or by a program, but first, I’d like to know: what’s this all about? How are they doing it (yet another cheat from the cheating software colloquially known as ‘deck trackers’, which I’ve never used, or something else, e.g. this whole player being a bot entirely… I assume tracking me via social engineering unlikely, since these requests coincide with matches) and what is the point (are they trying to be social or is it something for the purpose of data mining, e.g. from machine-spectating games)?
