After 14 years i've had enough, til now the main thing that kept me playing was my EC, since that's now closed to the public i have no reason to continue logging on every day.
a word of warning to other EC owners, admin supports trolls who abuse the extension request system (if you deny an extension the player can keep asking no matter how many times you say NO) but if you ask them, no matter how politely, to stop you're considered to be sending "abusive messages",
a FAIR option would be to make it the same as it is with friend requests, a denial triggers a temporary block from asking again, but admin don't believe that would be fair to players who don't like being told NO.
admin know this problem exists, they just don't care enough to rewrite a line or 2 of code...
until this flaw in the game is fixed my EC will stay CLOSED
