A big issue with 'games' like this is that anytime money is involved it's never in your favor. I consider game companies are either Proactive or Reactive.
Reactive companies see someone logon your account see some sketchy stuff (sold or traded everything away, empited your account sort of thing). They than lock your account after (in case the 'hacker' forgot to sell something maybe..) so you spend several days/weeks trying to get into your account again to be told.... Ahh well to late you should of had done this or that... Ina world that evolves as fast as it does, looking at support in general its pretty archaic in both layout and responses.
A Proactive 'Game' company would be checking as soon as you logon, checking and building a database if possible on your online times, IP etc whatever is legal allowed. If not they should or could have a series of account related security questions (emailing a code does little if they have already hacked your system and accessed that or you have no cell phone). but as saying goes.... Caveat Emptor
Now in reference I too have been locked from my account, past week or so I found. I have been playing for over 10 years so it can happen anytime to anyone... I haven't paid into the 'game' in about 8 years or more since PAYPAL was removed. I just used whatever I got from my CLD's and Arcadia deeds etc stuff to run a mining mission now and then. With all this happening around the CLD changeover is a good guess why more is happening or has to grab as many before they changed over.
Anyways sum it up, good luck on getting your account unlocked and items returned if any are missing.
