This is showing my ignorance of computer networks again, but here we go:
I work in a ‘mega site’ with God knows how many lines coming in and out. My question: Multi’s. If someone, say in the building over, or even in the next lab starts to play this game… will we get ‘red flagged’ as a Multi? Or is it based off of the IP address, which, in my case, changes each time I log in. And if so, … what keeps people in my situation from just logging onto different computers (or the same one over and over again) on a school/business campus with different handles?
Hopefully I did not just rip open an entry hole for cheaters with this question…
First of all, public connections are nothing to worry about. If you don't know someone else who plays from that location, >99% likelihood of there not being anyone, considering we only have about 3,000 active players at any given time. It has never been a problem.
As for IP addresses, yes, sharing an IP address with another user does alert us, and if you ever do you need to register as multis, but it is not the only factor that we look at (I typically look at 5-6 factors overall in looking to determine whether accounts are illegal multis). That's not something we give much information on, however, for what I hope are obvious reasons, but it also isn't something that players who don't have illegal multis need to worry about.
It probably is possible to get away with having a multi, at least for a very long time, by knowing what we look for and going to great lengths to avoid it, but in the end there probably wouldn't be much gained for all the risk and effort so I don't find that particularly concerning. It's less work for us than it is for them.
