Three questions...
1/ Im assuming ye were in open? Please say ye werent cos thatd be way cooler and would mean no need to read the second question, as the riddle is solved...ye need to visit specsavers. If yer in in open, then move to question 2.
2/ Are ye absolutely certain it was a player? A pic would be sorta ok, but a video clip would be ideal...anything less and its yer word against theirs unless ye kick yer suspicions upstairs with a ticket to the ivory tower, and they investigate. Is it possible? If yer curious because yer certain, then goto question 3...if yer confused cos ye just realized what yer caffiene/alcohol/THC intake has been during the evening, and ye dont have proof then...good luck.
3/ What platform are ye on? The reason I ask is quite simply that if such a thing were possible, it would mean different things to different platforms. PC fer example can run scripts whereas console gamers cant, though both platforms can mess with their router settings. Need more detail basically...its like trying to find treasure without a map, clues or a ship, just a sunday night drunken rumor...
