If you're getting "Nonstandard GTA file" warnings on your MTA diagnostic result, it means the file was either modified by you, another device user, or the game is not an original copy (i.e. it is a pirated copy of the game). To fix this buy an original retail copy of the game such as a Steam key from G2A. It's best to do your own research and on resellers though.
@DonNobody are you installing those mods locally or are you loading them using MTA server scripts?
If they're being loaded locally through gta3.img, you'll want to make sure that the server you're playing on allows custom gta3.img. It's disallowed by default.
You can configure this in server config which should be located in \MTA SA\MTA\server\. Since skins don't use embedded textures, you'll need both TXD and DFF.
Hi, I've checked this and there was no mistake made to ban you from MTA. If you feel you did nothing wrong, it means someone else is in control of your device and has actively been cheating on MTA.
I understand your intentions by including those links in your post, but unfortunately this cannot be posted within the public forums as it might fall into the wrong hands.
We are aware of the cheats and there is currently no need to provide us with any more information about them.
To touch on your concern, we do not want cheaters in our project and in this instance the ban remains permanent.
