Yes, that is how things are working right now. As a free host, we need to cover costs, and this is currently the best way to do that. If you wish to make a donating then use the donation link up top as that will help.
This is an idea that will only work if a large amount of Support members are working on 'shifts', so there is almost always someone on. This isn't something that will work well at VlexoFree for some time to come.
I have just checked and it just states 'Spamming'. I am assuming that you have been sending out spam from your account and that is why you were suspended. Doing that is against our TOS, so why did you do it?
Did you have ads displayed on your website? Do you have any other accounts hosted with us? The chances are that you aren't displaying the correct ads or you have the same IP as another account hosted on the server.
