ok, As a senior of group she is in I can tell you this. I've been monitoring this problem for a month or so I've been doing weekly growth statistics power/BA lvl +rank upg, donation, I found out more than 5 ppl were alts. We kicked them out, they keep coming back under different names.

To gnw: What can they do? As Noobity*ity said, if I put 6 men team in one field and alt is in the 4th slot, they could guess what stategy would we run.

One more thing our s280 is special, cuz only our side does SS convoys nowadays and alts of some ppl from their group (moreover bcuz they use autoclickers so its almost impossible to plunder them). Members of the other group dont do that since the other group officials banned them to that... So pretty much want us to have good gaming experience.. Its f**ked up, but what can we do? evel up new characters? no, thank you.
