I recently recieved an email from pokerstars requesting explenation:

"Hello XXXX,

We've disabled real money transactions in your account as it has come to our attention your association with the following players:

XXXX
XXXX
This association could've been the result of a shared playing location or deposit method.

To assist you in removing this restriction, please provide an explanation of your association with these players (if any).

We don't mean to imply any wrongdoing, but we have to carry out occasional security checks to make sure our website remains a safe and secure environment for our players."

I genuienly have no idea who owns these other accounts or how i have any connection to them. Just wanted to see if anyone had any other tips since I am waiting on stars for a response.

Normaly this means that the players in question have a problem / debt to Pokerstars / have been banned.
It's possible you have shared IP / pc with them if you have played from a public WiFi or computer cafe ?? Or maybe you have bought / sold currency to them using the transfer function in the pokerstar client ??
This is now a red flag for Pokerstars because maybe it's the same person behind all the accounts and this is why your account is being investigated.

Warning.: Do NOT just send them an e-mail saying you know nothing about this because Pokerstars have extensive LOG systems.
You need to give Pokerstars an explanation or ask for more information.....

I have received these in the past few times and I have done what hsd told not to do. Told them I don't know these players / never played with them based on my db and after few days my account was opened again. This is was when stars support was good though. These days I think the best solution is to dm starssupport twitter. Fwiw never received any reason why my account as flagged with them. Don't use any public internets or share my connection with anyone or play with someone from the same ip.

Just answer their question completely and honestly. Hopefully you will be able to access your account in under a few weeks.
