Some conspiracy theories turn out to be true. Suppressing research into these would also lead to poorly informed decisions. For example, government mass surveillance on the scale revealed by Snowden was considered a conspiracy theory before the proof emerged.
So I would disagree that "conspiracy theories are problematic." Some are problematic, but there are also some that turn out to be extremely important. No progress is made without questioning authority and the status quo.
