Actually, my main original purpose was to call (more) attention to the fact that looking for somebody specifically advertising a VPN to your particular country, for a censorship-resistance purpose, has a vastly greater chance of getting you a honey pot than almost any other possible way of looking for a relay. Honey pots are particularly dangerous in one-hop protocols with cleartext exit.

The part about the unreliable ad-hockery is also true, albeit less critical. The fact is that you don't know what your adversary is doing now, and you definitely don't know what they're going to to roll out next. You don't have to be stupid to decide to take that risk, but you also don't have to be particularly stupid to not think about that risk in the first place, especially when people are egging you on to take it.

The greater purpose underlying both is to keep people from unknowingly getting in over their heads. I have seen lots of people do actually stupid things, up close and personal, especially when given instructions without the appropriate cautions.

And "services and providers" doesn't necessarily mean commercial VPNs. In fact those were way down the list of what I had in mind. Your own VPS is a "provider". So is Tor or I2P (not that those won't usually run into problems). So is your personal friend in another country.
