Here is a scam report from user of ultramagnetictees.com:
I was scammed by the owner of ultramagnetictees.com. I was wondering
if you would post a summary of the events surrounding his criminal
behavior on your site.
I give the full account on a gripe site I posted at www.wondahshop.com
(a former domain of the scammer’s that ultramagnetictees.com still
links to, hee hee). I would be more than happy to post a link to your
site in exchange for a short article here.
