I would like to add that HTTP itself is not a red flag for websites and should not be considered a bad option. If you use standard HTTP proxies (properly configured by your proxy provider), everything should be fine.
Btw we are seeing an increase in demand for UDP. It can reduce the risks of detection. But honestly, sometimes it seems more like a trend than a truly informed choice of protocol. Because simply using UDP does not guarantee reduced detection risks, as a lot depends on the configuration.
In fact, no protocol by itself is a magic pill that protects against detection. I am sure that HTTP is stile alive and quite fine.
