Fraud signups attack - what would you do?
 

First of all, I'm a calm person and I'm never involved in any dramas or online wars, so this is very frustrating to me.

Somehow I've triggered competition (??) attack on one of my blogs, and the attacker has started sending me lots of signups, probably trying to compromise my affiliate accounts with sponsors.

This is how my usual sales pattern look like:

This is how it looks for the last couple of days with attack:

Most of the sales are coming through the same BLOG, same CAMPAIGN. It looks like a guy just goes through all the posts and makes 2-3 signups with each paysite/sponsor.

I've already noticed all the sponsors and some of them already refunded transactions, while others told they gonna investigate with their billing processors. Pimproll and AmateurTraffic were kind enough to tell me that those sales do look like they're coming from the same person.

The shitty part is that the attack isn't over, today when I woke up and ran NiftyStats, I've got 20 more sales coming in, through the same blog/campaign again.

What would you do in this kind of situation? How would you protect your site and your affiliate account?

Close the site temporary? Change links? Remove links? Or do nothing and just report all the fraud sales to sponsors? But what if this crook keeps doing them? How to protect from such behavior in the future?

Any ideas are welcome

I'd just wait it out. Keep the sponsors in the loop. He'll move on.

What he said... :2 cents:

Weird situation,except working closely with sponsor dont see other alternative.

That's crazy...hope it turns out okay for you.

congrats on working with liars and fraudsters. go fuck yourself

and cb's in 3.2.1....

I'd let all the sponsors know. They usually know what to do.

It seems very likely that there may be more to this story. It is costly to sustain an attack like that, even stolen card #'s cost money.
