StackOverflow moderators keep migrating "which hosting company should I use" type questions here, and they usually get voted down. Pro Webmasters seems like a more suitable place for them to get voted down. How to get StackOverflow mods to start using the other StackExchange sites?
In addition, there are more valid questions such as "what should I look for in a web hosting company?" which end up at ServerFault. There are plenty of people here capable of giving good answers, but then that probably goes for any of the StackOverflow sites.
I personally do not believe these belong on any SE site. They come under the bracket of "Subjective and Argumentative", as you are always going to elicit different responses from different people, and often just attract spam as chopper said.
I was just talking to Pauska about this subject on chat - I totally agree that they don't belong on SF (same for SSL cert ones) - they're just spam-bait too. Not sure what to do with them to be honest, if someone edits the FAQ to state we don't do them I'm more than happy to just close them myself - though that might be too harsh.
