So in summary this is how many times it changed:
1. pulled out of line at Phuket airport because "white" guys are suspected of fake boarding passes if returning from Kuala Lumpur
2. after waiting 30 minutes, my paperwork was found to be real, so the grumpy sadistic supervisor started screaming at me to sign a confession that I didn't have enough money
3. I refused to sign and asked him what's the reason he wants to deny me, tried to show him my money but he ran away and hid in his office
4. Young (kind) intern girls wearing uni uniforms came over to try and help me, explaining that this supervisor was always grumpy and they saw him do this on a weekly basis, and that I should hurry and book a ticket back to Malaysia and next time arrived to Thailand by Laos or CM
5. Arrived back at KL airport, the airport staff from VOA office tells me they have heard such concerns from Phuket police recently, suspecting some foreigners to be landing in KL airport but never exiting the airport and returning to Phuket (I have no idea how or why anyone would do this)
6. Arrived to Nong Kai border, the police have limited computer access apparently and they couldn't understand the warning on my profile and recommend me to fly into Thailand
7. Chiang Mai police dig into my profile and discover this warning in my profile was essentially spiteful and incomplete, I assume aimed at trying to confuse future IOs who dealt with me (successful I guess)
8. After confronting this supervisor on the phone directly he changed stories yet again saying that I didn't explain my tourism plan and therefore I was denied entry
