Why There Are No Measures To Prevent Cheating?
I think there are not enough measurements to prevent cheating. Of course it is not possible to prevent cheating in fps games but with some measures I think it is possible to reduce it. For example:
1) There can be a prime account system to play ranked above a certain rank which requires a credit card and sms verification.
2) Hardware bans can be used to prevent same people from cheating. Of course there are ways to bypass hardware bans but measure is a measure.
3) Player should lose all RP if he was in a premade party with a cheater. This will prevent most of the boosters.
4) Games above diamond can have additional requirement like level 200.
5) Players who got killed by a cheater team and lost rp can have their rp back. It won't help prevent cheating but at least people feel less frustrated.
6) Anti cheat can be more agressive and get more recent patches, even fake patches will help since people will fear losing of their account and may stop cheating for few days.
