I guess, sometimes, people need emergency cash. That's why they were selling it for cheap. However, there is no one selling at a low price at the moment.

Moneygram limits 3k/month, in one year, it'll be 36k. Combining with other services, the total balance can go up to 100k. Will the government keep an eye on you as you send a large amount like that every month? Who knows if that seller is using the money for doing bad things. The point is doing that legit and staying out of trouble.
