On More realistically, I think this might be due to misconfigured Orbot proxies. I just had a look at the Orbot source code, because I remembered them mentioning they wanted to allow users to use snowflake as a Tor PT and behave as a proxy:
https://github.com/guardianproject/orbot/blob/920a4e30a6624bc79eeef252a30cf9...
The IptProxy source code uses a patchset on the Go proxy code and it looks like they aren't changing the proxy type reported to the broker:
https://github.com/tladesignz/IPtProxy/blob/master/snowflake.patch
So my guess is these standalone proxies are from Orbot users, which would also explain why many of them also have restricted NATs as meskio pointed out :) I'll reach out them about it since I have a draft email about other IptProxy work in progress.
Looking forward to it!
We do have the capability to be a Snowflake proxy available in Orbot as an experimental feature buried in settings, but are not promoting it actively.
