At first, I planned to use it for email newsletters, but they are prohibited here, as well as spam, mass account registrations, and similar activities. In general, their list of prohibited actions is quite long. I agree with the restrictions against fraud and hacking, but they could allow some gray purposes. In the end, I have to use it only for parsing. I don't have any major complaints about the proxies, although a few were non-functional when I purchased them, but they replaced them for me right away. The speed of operation is above average: websites load about the same as with a regular connection. I haven't noticed any problems in the work, even though I've been using it for more than a month.
