As fide rule 9.2 states:

The game is drawn upon a correct claim by the player having the move, when the same position, for at least the third time (not necessarily by a repetition of moves):

a. is about to appear, if he first writes his move on his scoresheet and declares to the arbiter his intention to make this move, or

b. has just appeared, and the player claiming the draw has the move.

Positions as in (a) and (b) are considered the same, if the same player has the move, pieces of the same kind and colour occupy the same squares, and the possible moves of all the pieces of both players are the same.

Positions are not the same if a pawn that could have been captured en passant can no onger be captured in this manner. When a king or a rook is forced to move, it will lose its castling rights, if any, only after it is moved.

Now lets look at the black moves 61-64-67-70:

I pressed the draw button both on move 67 and 70 ( 4th repetition) , but instead to get the draw, my opponent moved refusing the draw ( WTH?!?!?!?!? ). While i can imagine that it does not happens so often what people recognize a non consecutive treefold repetition i was very surprised that chess.com have not implemented this type of checks. For a portal that claim to be the best chess comunity, and a place where lots of title players play i think its fundamental stick with the rules, especially when its not hard to implement. How could be difficult save the FEN for each move and then compare the FENS uppon draw request?

Actually this is a good point and not spam for once. Weird I've never encountered a non consecutive before, must be like a BNK v K with no pawns ending. C.c should probably find some code to fix/enable this

Well, i knew there will be a repetition because i know this pawn ending and how to force a draw using the opposition. Since my opponent wanted to continue ( probably he didn't know that there is no way for him to promote, or was hoping a mistake on my side) the repetition just happened.

I knew i could force it.

I saw the start position that you showed and I know its a classic draw
