You will get locked if you linger in a f2p hotspot on a datacenter proxy. If you find you're getting locked as soon as you log in, it's time to change your entire setup because your IP/MAC may be flagged. Besides that, datacenter proxies appear to be one of botwatch's first priorities, accounts operating on them will almost certainly be profiled and banned before resi. It is possible to succeed with these IPs, but it will take a lot of testing with different providers, preferably a provider no one else is botting with. If you have a dynamic IP, try your home IP, make sure it's different from your main accounts'. If your home IP helps, you would do well to get a few cheap used laptops off of amazon/ebay or something and assign them each a resi IP from your own home router.
