I didn't see the prohibition of promoting them before when I posted, and I'm curious to know why.
HG is fine for you to use, no one cares what you do, but stating you use HG is an automatic warning flag for a bunch of people who work online. If you have to ask why, you know you're new. They are budget and cut rate, and make up for that by having customer service. Product doesn't cut it? Make sure you do something well. And throw the little people a $1 deal, they love that, especially when they ask "How do I invest $5-$50?" If you cannot afford a better host, cannot be bothered to find a better host, do not care that they oversell and put a lot of shoddy sites on the same neighborhood as yours, get entire IP blocks blacklisted, and have questionable affiliate practices, that's fine. I'm sure you can convince the newer breed of IMers and clients, but not people who have been there-done that and run who away from HG, ipage, intuit, GD, bluehost, fatcow(heard they're dropping rank), justhost.
But, what is the reason for the prohibition? Are they xrumer blasting BHW? Or is it the case of "yeah. .i use gsa and snuke. is great for build backlink 2.0s to get social signals" newbie parrot flooding?
