cheaters and engines

i could experiment some engines , played vs on lichess, im new on chess dot com , and the 10 minutes games are infected by cheaters using engines...on my side i can recognise them they take looong time to play, almost abandoned game, and then they play...so i wopnt play anymore in ten minutes still chess dot com or lichess find a way to detect those engines or analyze games to consider than over 5 min you find a lot of cheaters. prefer loose fighting than play vs cowards
