Thank you for your concern.
The "local" forum moderators can be contacted:
Clicking on

pops up a message box; the message goes to all Moderators of a forum, or to the four Senior Moderators if there are no appointed Moderators. Note that unlike some sites with paid staff moderators, FlyerTalk Moderators are volunteers, and most work, travel, go on holiday, etc.
If there is one Moderator, or it's a big deal like this spambot explosion, try sending a PM to the forum Moderator(s) and the Senior Moderators: currently,
