Possible reasons why Tantan can slide to users in Thailand include:

1. The user may not have changed the system’s default address when registering Tantan, and the system’s default address is Thailand , so it will be displayed from this place.

2. Even if the user does not select Thailand as their location, Tantan's algorithm may recommend people from Thailand based on the user's interests and behavior.

Please note that this is only a possible explanation, and the specific reason needs to be judged based on the user's specific situation and detailed information.
