Iran-based pollsters
According to the Al-Monitor, "it’s not unusual in Iran for news outlets to publish reports of nonscientific surveys. Without further details, such polls shouldn’t be considered reliable if they lack the disclosure of basic methodological information". A persistent problem in Iranian pollsters, they also do not report the standard disclosure items for legitimate surveys including sample size or margin of error.
