best bit of advice i have ( learnt from experience) is make sure your controls etc are sorted before you go racing.

also don't go racing on the more serious servers like ctra untill you are fairly competent at staying on the track, ctra have brilliant servers if you want to improve your driving as the points system and the reset restriction encourage you to race clean, it's the closest thing i've seen onLFS to iracing's sr system and generally the races are very clean and polite.

hopefully you've learnt the first point yourself by now, use your ctra ban as time to learn how to stay on the track at other servers and then go back to ctra, start towards improving your licence and enjoy yourself
