As far as I can tell from a tracerout, the server for this forum is located in the US.
Under US privacy laws, a user has the right to have his / her account and all private information deleted if he / she requests that - no questions asked.
Posts in internet forums are not covered by this, but the user has the right to get his/her posts disassociated from his/her account.
Laura could therefore simply rename the user account to "deleted user", delete all other information from the account (e. g. age, location, whatever was asked at the time of registering the account - and that should suffice.
