You have attempted to post your client's email address on a public forum. Thankfully the forum redacted it.
You have actually posted the account's activation code on a public forum. Doing that is unbelievably irresponsible! Anyone with the activation code can use the account and access your client's information. The account has been disabled.
It seems you have no respect for your client's information or their account.
If you need assistance with an account, do not post the account details publicly and especially not the activation code. Instead, contact us privately at: contact@esotericsoftware.com
