Just some info for others worried about entering.
I've spent the last 3 years on/off in Thailand on tourist visa, visa exemption, and a 1yr student visa.
I recently left for 9 months and did a world travel trip.
Yesterday I crossed via land at the Padang Besar border with Malaysia.
No issues at all, despite the many Thai stamps in my passport.
No questions, no proof, nothing.
Just a photo, fingerprints and a slightly grumpy officer, and I was stamped in for 60 days 👍
