"that do not accept clones"
...meaning you're not only most likely using proxies without authorization (which is essentially illegal), but you're violating the rules of a network. Last I checked, breaking the rules is "forbidden" on most networks.
The reason most networks don't accept clones is because they don't want multiple connections from the same machine.. It's not just about an ip address. Connecting through a proxy doesn't change the fact that you're connecting from the same machine. At least admit that you're aware you're violating the rules.
In any case, you shouldn't need proxies to insert *a* (one) bot onto a server. That would be a max of 2 connections if I'm to assume your bot would be on its own connection.. I've never seen any servers block access to anything under 3 simultaneous connections, so it shouldn't be a problem. If the server *does* block 2 connections, this is something you need to take up with the admins of the servers-- it is not a rule you should evade on your own. Out of curiosity, what network is this that only lets you have one connected client at a time, assuming you're actually telling the truth?
