Inquiries about phbot residental proxy

hello … i wanna ask 2 question 1st : how many pc i can use the phbot proxy on it at the sametime … for example i have 3 pc if i buy one phbot proxy will i be able to use on the 3 pc at the sametime or only one at a time ? 2nd : did anyone tried phbot proxy vs the new blockage of proxy / vpn filter that most of private servers applied inside it … i think its max guard thing … will the proxy successfully work in any of those servers that applied that kind of blockage or no ?
