I've just posted a question basically about whether or not it is allowed to reenter a country in South America twice within a short period of time.
Admittedly, this question is based on a statement, that I was never able to prove, which claims that some countries try to ban Visa Runs.
Assuming this statement was correct, I was wondering if it makes sense to create a general wiki question. That would have one answer that would list all... a lot of countries in the world that have applied such a limit.
If this is feasible at all. I'm not even sure how to obtain a definite answer for a particular country, much less a whole bunch of countries.
