If anyone tells you that goldinc.com is hosting porno, they're misrepresenting the truth. That is, they're lying to you.
Chances are, the person(s) who maintain, purchased and/or broke into webtechs.com are also the same folks who pointed out the "porno link on goldinc" to you. According to an altavista search from earlier this year, at least 30,000 sites were linking to webtechs.com (the HTML validation service).
If someone telephones you in a lame attempt to get you to change your web site hosting service (because of a link to webtechs.com on some HTML page somewhere), please note their name and number! We'd be very interested in that information.
