We have seen this happen before but we need to send you a reminder. You may receive a direct message. or even see threads promising free AP, or with a link to verify your account. Please remember do not click any links. This could lead into a compromise of your account. This could be in the form of a GS account or a GM or even Admin accounts.
Staff here will never contact you via a PM or a thread about your account. They will always contact you via email with the same address used as is used in tickets.
If you are ever in doubt the GS team is always on your discord contact them to question and/or report any activities you may deem suspicious.
Also I would suggest you to in to your account click your avatar top right for control panel:
And do the following
You can also disable the pms if you click your account then the privacy link and disable pms.
