It could just be being blocked because it's not a site that has any reason to accessed by the employees of said companies. The adult/phishing message is probably just a generic message set by the IT staff.

Sometimes you can get around this by having an alternate domain pointing to the same forum (easy on VB3, possible on VB4, but not possible on VB5.)

In that case you get a domain name that sounds somewhat professional so it doesn't stick out if someone is reviewing a list of accessed domain names and only share it privately with those who get blocked on the main domain name.

You need to "park" the additional domain with your hosting account.

Example- my forum is juot.net but for years an alternate domain was poisonwoodgroup.com, even though juot.net was flagged at many people's jobs poisonwoodgroup worked for years.

Some firewalls can tell its a forum and just block all forums if set to, regardless of domain.

The people who did get fully blocked at work just access via their phones these days.
