People on Reseller accounts have limited space to sell which could effect the sites performance. It's not cheap to maintain a server and make sure it always has the latest and greatest hardware and software. Also providing 24 hours/7 days a week support which should be excellent. People who have no clue how to run a web hosting business nor have any experience about the inner workings of servers and how to tweak them for better performance should get out of the hosting business. To run a legit hosting business that will continue to grow large, you need to know your stuff.
I thought about starting one up 5 years ago but i didn't want to purchase a resellers account. I wanted to start one from scratch and purchase all the software and server...etc (Then i just created a blog that i run now which don't cost me much but the cost of a VPS server)
It's ok to create web hosting threads in the correct section following that sections rules. Now if the same person is creating multiple thrreads for same hosting plan every single day, then i'd be worried he or she has hardley no business and hurting for money to break even each month. Use adwords and spend money to make money if you want to make your hosting site a success like the top dawg's.
Since it's now very hard to do good in the web directory industry after some folks ruined it, they finding a new niche to tap into and prolly get it in trouble with Matt Cutt's. lol (He wasn't to thrilled with web directories a long time ago)
FYI, when you see a web host with a pre-made template, that should be a red flag to close the browser window.
