I will never ask for your hosting account details to provide you with support. I don't need them to check what's going on with your account. Be EXTREMELY careful with your username and password as impersonators might ask you for them over unofficial communication methods.
I randomly perform websites inspections to make sure that all hosted content is compliant with our ToS. Remember that using this service to host disallowed content might lead to receive a warning and/or immediate termination without refund.
What you're purchasing here is safe and private web hosting that allows you to manage unlimited domains/subdomains. Sale price can also be reduced using the coupon code at the top of the original post.
