Just thought I'd share my experience getting a new DTV stamp for the first time as I worried a little about it given the increased scrutiny with (short term) tourist visas as of late. I left thailand for 3 days to Cambodia, and got stamped back in for another 6 months without a hitch (as expected). I have a DTV under the soft power activity scheme and I thought they might ask for some proof having attended the events (which i could provide) but nope, no questions asked whatsoever. So this is just to put other people at ease, as I've found these type of posts helpful to decrease my own stress on the matter as well.
