You can overstay 20 years. You just pay the 20k Baht and you are welcome to come back. This has been well documented on ThaiVisa - people overstaying huge amounts of time and every time they report back no issues, they don't get blacklisted etc.
Just don't get picked up in country, then you may face criminal charges and be held at the immigration jail until you are deported.
