"I don't need to look up the rules." ++ Then believe me.
"Chess.com isn't making up rules" ++ They use something easy to implement.
"they have to be using something like FIDE or USCF rules" ++ They implemented neither. They implemented something almost like USCF. The other site did not implement FIDE, only something close to that.

"Then believe me." Well, are you a USCF TD?
"They implemented neither." Do you have proof? Do you work for chess.com? Have you asked someone from chess.com? Or are you just saying this to try to win an argument?

In that position the bishop is sufficient to checkmate:
@24
This is the USCF rule:
"14E2. King and bishop or king and knight.
Opponent has only king and bishop or king and knight, and does not have a forced win"
Chess.com only implements the part before the comma.

In that position the bishop is sufficient to checkmate:
I know that. I said that.
@27
So there are 4 sets of rules:
The position @1 of the original poster is a win by all 4 sets of rules.
The position @25 is a win per FIDE and on the other site, but a draw per USCF and on chess.com.
This position is a white win per FIDE, and USCF, and on the other site, but a draw on chess.com:

"believe you about the rules?"
++ Look up the USCF rules and see for yourself.
I don't need to look up the rules. It just takes a little bit of common sense to know that Chess.com isn't making up rules, so they have to be using something like FIDE or USCF rules.
I've had a tournament director rule on my game before in a USCF game like this:
I was playing black and I flagged. My opponent thought it was a win, but I thought it was a draw, so we called the TD over. The TD said it was a draw, even though there was a possible mate, because a bishop and king is still considered insufficient material to mate.
