I have created 50 in a day, but never tried more than that, because I don't need to, and don't need it.
But the support is slow as hell, most replies on skype are one line answers and it's a bit annoying.
If you can stand the long waiting time for replies, then you'll realise that the support is actually helpful. I am pretty sure that the OP is using a VA to reply me because sometimes he types in a weird english, and sometimes he types nicely.
Also, to be honest, there's not much written in the .pdf file and you have to figure everything else by yourself, so the first 10 or 20 or 30 proxies and emails you'll be using is for trial and error.
I'm not trying to say that $90 is a lot, but I expect a better support than what I'm getting.
