Will Chess ban my account for stuff like this???

a4 was me giving my rook some space, and I usually play moves like that when I'm waiting to see what my opponent will do, cause its a developing move and not hurting me in any way, and I played c3 cause he took on e5 meaning I can't play c4 to trade pawns and threating his queen on d6 when I take on c4. So c3 was just developing a piece again. All I've ever heard is that high accuracy like that means cheating, so I was just wanting some feedback.
In a game of rapid my opponent accused me of cheating when I had a 97.6% accuracy and he had an accuracy of 93%, we both played a good game and overall I felt like I was the better player, we also both had an estimated ELO of 1800 that game. I'm rated 1100 in rapid.
Thoughts??
