Are all opponents on chess.com actual real humans?

I had some weird games of Blitz today. Some incredibly strong opponents who knew the main lines of unusual openings , and all rated around 1600-1700. Their accuracy was 90% + most of the time.

Then, just as I was getting really sick of losing , along comes an opponent who is really easy. But easy in a weird kind of way. The bad moves just made no sense at all. 

This opponent played me SEVEN times, letting me win 6 games easily, and never seemed to angry (real people would just quit, send a rude message or let the clock run down, unfortunately). Instead, he/she/it just kept on asking me for rematches. Again, this is very odd. Normally, with real people they tend to ask for rematches when they WIN or when they lose in an unlucky way

I sent some chat messages asking if they were a real person, but no reply.

I looked at the profile and (as is often the case with these weird opponents) they had no information on their profile and were a member of "chess.com legends club", which has over 2 million members. Very odd

Some people aren't very communicative.

Some people play when they are inebriated.

Your opponent has been playing a lot of blitz for the last 11 year. 83,000 plus games.

/ It is impossible to prove but I still think that they are all human.

okay, thanks for the reply!
