I'm running zennoposter to post to web2.0, blog sites. I've been using a VPN but now that I'm upping the thread count I want to use private proxies instead.. Let's say I'm making accounts at livejournal, tumblr, wordpress etc and I want 15 accounts on each, I would buy 15 proxies and use a new one each time. But let's say the next day I want to do the exact same thing.. are these proxies gonna work for me or are certain sites going to start blocking me from making new accounts.. I'm only used to having thousands of IPs at my disposal so I'd be very interested to hear from someone who uses private proxies and can shed some light at their actual lifespan.. Thanks! Sorry about format - I had spacing but it just crammed it all together..
