Is visiting Thailand multiple times a year problematic for immigration?

Visiting Thailand multiple times in one year, especially for short stays of under 7 days, may raise concerns with immigration, depending on the discretion of the immigration officer. While several commenters noted that frequent short visits are generally acceptable (as long as the total does not exceed 180 days in a year), they also pointed out the potential perception of abuse of visa regulations if the pattern appears to suggest illicit intent. Many shared personal experiences indicating that as long as visits are perceived as legitimate tourism, there shouldn't be significant issues.
