This morning I saw a bunch of regular GameTZ traders show up as being on the same IP address.
The IP address resolved to a name server with ztomy.com at the end of the host name. For example: 18.104.22.168 (ns1504.ztomy.com) and 22.214.171.124 (ns1504.ztomy.com).
I googled a little for ztomy.com and found them associated with domain name hijacking cases in the past. In other words, your computer or device has its DNS redirected through ztomy's servers and then they control what sites you actually see (e.,g. you may try to load google.,com, but instead you get a ztomy host that can inject whatever it wants you to see). Presumably to give you malware or other dastardly things.
There were about 8 GameTZ people affected by this. It was all at once this morning (didn't see it yesterday), as if suddenly a virus was spreading reapidly... kind of scary. But, I could just have it all wrong too (doubt it).
Anyway, if you're seeing strange things... it may be your DNS settings and you might want to run a virus checker or malware fixer...
