Yes, the 2 accounts from the same ally are connected through sitting.
The 3rd account that got traded with and then raided has no affiliation with the other 2 accounts, other than a minor trade, before being raided.
After further consideration it also means:
At some point we can't raid let's say 10% of the players on the server.
Or it can mean that people can exploit trades, by accepting a trade from us, and then they have immunity from us for 2 weeks, without us even knowing.
Ok because in the original post you talked about 2 accounts and now you are mentioning a 3rd, can you explain again what happened?
