Affiliate fraud question

I might be dumb for asking this but if i would find a lets say a saas company that has a plan for $10 a month and as an affiliate you get $30 could I just share my affiliate link on social media and click it from a proxy, correct timezone, new mac address, user agent and a new SIM..
Then buy the service with a fresh paypal that i created with that SIM, use the service every other day, how would they find out?
Does every big company use a 3rd party services to detect fraud or do they just have a simple system that removes low quality leads (same IP, payment method ...)?

it won't be long until you get kicked out of the affiliate program.

They will see that the lifetime value of the customers you deliver is very low.

Also, you need to get paid as an affiliate don't you? So your signup details will match the payout details, won't it?
Self-signups are against the terms of 99% of affiliate programs.

Don't try to play companies. Provide value and get paid in an honest manner.
