Accused of using computer..common?

I was playing a casual unrated game, playing very oddly for fun. Fell behind and made some unusual but in the end pretty good moves. The opponent said I was using stock fish or Komodo or something. Now I have never even heard if or used something like that, but is it common? I analyzed the game after and according to computer made plenty of bad moves,,,

i used komodo or stockfish before in a tournamnet here at lichess... it was detected after two games of cheating .... now i have a new account .....

Just say 'thank you for your compliment' or 'awesome' or something like that to make them angry even more (of course, if you genuinely don't use assistance, which I am sure in, though). :)
