Hello RONINFILIP.
You cannot appeal for console bans. Client Modifications is the anti-cheat flags, it detect and kick/ban people with cheats, but it can sometimes be false.
Here's a list that will reduce the chances of getting false kicked/banned again:
- If you are using an early version of minecraft 1.14+ - 1.16~, then I recommend using 1.8.9 for a better gameplay in general.
- Make sure to keep your CPS lower than 20 CPS+.
- If you have a high ping 150ms+, try getting a better internet connection.
It's not always your ping, mc version or CPS. It can also be the server lag or a bug, so all of need to do is recording the bug and reporting in here.

Have a great day/night,
