Who here has tried their shared hosting and added more than 100 mysql databases or add on domains? Does your account still run without any problems or slowdowns?
I have their $10 plan...i think it's called the baby-croc or something...I only have 13 sites hosted with them, but it seems stable so far...only been with them a month though. To answer your question, I don't have more than 100 domains or addons, it shouldn't matter though since it is a shared server, they can move sites and accounts around to reduce server load.
Your account should still run but if you are using too much of the server's resources they will suspend the account. There isn't really a hard limit where you can say "this is too many sites" as it depends on how much RAM/mySQL/processor cycles they are using.
They truly offer unlimited domains hosting- not like others which claim and do not do so. As theHoff said, as long as your sites do not use too much of cpu resources, you should be fine
My only worry about trying to host more than say 50 domains would be that they cut you off unexpectadly and then you're stuck trying to recreate all those websites on anouther host. Is there a way to know how much cpu resources you're using?
if they suspend you they will move the sites to a dedicated or semi-dedicated server if you are planning on getting any real traffic, safe your self some grief and don't buy the $10 account
ferret77 -->> good point. Also I've had hostgator up to about 52 domains with even more databases....
I had a shared plan with over 1,000 SQL databases with zero problems. Can't speak for the multiple domains though.
