I've just had the same experience on my server.
A carrier one "new player" took a name similar to "new pseudo", with an assoc name clearly indicating his anger at the support. And invested a slight 45M in one of our industries, in era 4. No trains, no nothing.
Awesome. I guess I might start doing the same thing to my opponents on the SoE server, since apparently there is no other option.
Do not bother contacting support because they do not do anything about it.
The situation at the Japanese server was never solved, none of us got any update from game staff, another round started, and now we have player sending obscene private messages, reported to support staff several days ago, never got a reply...
The situation obviously got out of hand, they are unable to deal with disruptive players, fake or real and their solution??? They are closing the Japanese server.
There will be no more Japanese server after this last round finishes.
Very, very frustrating!!
