If you don't have issues with your current hosting, keep it. I myself have 3 hostings, 1 is paid and the other 2 are free, including this one. I keep my important sites on my paid hosting and keep test sites, redirects, etc on free hostings.
I guess the banning has something to do with blackhat activities.
Btw, their support is responsive, although they're not quick to answer inquiries. But they do answered my questions and helped me set a few things up.
My free hosting account is now working. Their hosting is in UK, I think...so, IP address is UK-based.
