I'm certainly not trying to scare you into doing it,
I know people who didn't do it, left the country, came back and did their next 90 day report no issue at all,
BUT
I also know people who didn't do it, left the country, came back and got caught out when they went to do their next 90 day report and got fined the 2000baht and then were allowed to do their next report.
