Hi Andy1369.
Sorry about your difficulties here! FlyerTalk is meant to be an enjoyable learning and sharing experience and something of the nature you report is definitely not acceptable.
As BLI-Flyer mentions, pls report any stalking posts or Private Messages to a moderator in the forum(s) where they occur. The moderator will then look into the situation and take the appropriate action to make sure such behavior is halted.
The important thing is that you supply as much detail as possible to the moderators so that they can get a sense of exactly what the issues are.
Thanks.
