We understand how annoying this is, but unfortunately we can't help this. It is not necessary to have an account on Sexjobs to be able to give reactions to advertisements. This means that not everyone can be traced by us. Of course, you can always forward us the unwanted e-mail. If the sender is known to us, we will note this in the account. Whenever we see the need to, we will act on this.
If stalking really becomes dangerous, we recommend you to report this to the police.
