How frequently can Indian citizens utilize the visa exemption to travel to Thailand?

People saying "depends on length of stay" how does this affect it please and when does it come into play?

It depends on your length of stay each time.

The people of thailand are looking around the world and seeing the problems. Im not saying its you personaly but they have one faith and that they will protect unlike the west.

You are already lucky you did all these trips. Your passport is unfortunately not the strongest if I can put it that way, so don't play with fire and get yourself a DTV visa.

7 times in 4 years is a good tourist routine as long as the trips were not long trips

While visa exemption still exists for Indians passport holders it will depend on how long you have stayed in Thailand on each of your last 4 trips. But be aware that once the changes, which have already been approved by the Thai government, come into effect Indians will no longer be able to enter visa exempt, they will have to purchase a 15 day Visa on Arrival. We don't yet know when this will come into effect

Visa exemption ends for Indians very soon, you may get 1 more trip if you are quick

Unlucky......
