It means you have used a spoofer in the past. Perhaps to evade a ban for another game in the past. If you undo those changes, you should be good to go. Alternatively, reinstall your operating system.
You haven't been banned in a server or MTA during that timeframe, and it looks like the error you are getting is a connection issue so I have moved this into the client support section for you.
The ban for cheating is correct. If you feel you didn't use any cheats, it may be someone else who were in control of your device who used a cheat on MTA.
To be fair this is the second time you are appealing something that was allegedly caused by others sending you cheats.
As a general reminder it is the device owner's responsibility to make sure everything installed is OK to be used with games like MTA.

I have merged these two posts together as they have the same serial. If you are the same person, please remember that only 1 user should appeal a ban.
