While this is only a partial response, I hope this kind fo topic could be added to the pinned ones.

If the moderators could help by providing few informations, the better, thank you in advance.

The first step is, off course, create a ticket. After the form, you will received an automated response with a ticket number, for The mail address is [email protected], do not reply to different ones as the hacker might send you fake mail to gain informations from you. The timeframe for a response varies from 1 to 3 working days (so far).

The second step is to try to salvage what possible for the account: (Note that this doesn't work for  everyone, it's just my personal experience)

In case of the plarium account hacked, and the account is binded with facebook:

1- log in with your mobile

2- do the tutorial, then go to the account details by clicking on the avatar in the top left of the screen

3- log in with facebook.

This will allow you to log in again into your account. At this
point the hacker will be kicked out and will probably try to log in
again. You will need to click on re-login as many times as needed to
keep your account safe. You can download an autoclicker for mobile and
set it to click every 5 seconds on the position where the "re-login"
button riappears. In the mean time, log a ticket with your details, we
will either lock the account until ownership is proven, or fix it
direclty for you. 

The third step: reply to the ticket, providing informations about your account that only you should know, and proof of purchase if you are not F2P.

Here is what I lack the most: I don't knwo what is needed, which informations required and so on, so I hope a moderator could help with some informations.
