Sorry but that’s just not the case. There has never been a limit on how many visa exempt entries you could have.
There used to be a limit on the number of visa exempt entries you could do via a land border but that changed ages ago when the exempt entry was changed to 60 days rather than 30.
It’s up to the individual immigration officer you hand your passport to as to whether you can enter. If you’ve had 3 this year they may question you or deny you, but that’s the same if you’ve had 10 or 12.
Some people come for a week and leave, and repeat that each month or so. There’s not an issue doing that until the officer says there is.
