Other Sites Have Similar Problems
Stack Exchange is a community of people looking for help with their problems. Why don't we ask other sites for help?In fact, I'll even offer up a site that I know.
Max Barry's NationStates and WA Multies
In NationStates, there is an organization called the "World Assembly" (used to be United Nations, until the Real UN got mad), with the following entries in the FAQ:
I have more than one nation. Can they all join the WA?
No. While you can have as many nations as you like, only one may be a World Assembly member at a time.
What if I sneak them in?
First, please don't. This is against the rules, and considered cheating. Sophisticated pattern-matching software constantly scans for suspicious behavior and will expel nations from the World Assembly that it determines are likely to be cheats (known as "WA multies"). Repeat or large-scale offenders are deleted.
I know from experience that they are not bluffing; the mentioned software is the product of 13 years of work and is pretty reliable. There's even a similar motive for doing this: the requirement of "endorsements" from other WA members to submit proposals, become a WA Delegate, or gain Regional Influence faster.
So think about it: another website had a very similar problem, and they spent a decade making advanced software to fix it. How about we ask them for help?
