These forums are hosted in Canada and not on free speech per-say; it has always been moderated and your ability to message on them is gifted from the likes of Rugger and myself. There is no magic constitution on here; just what a few random people from different corners of the world decide together... but rest assured if you ever have issues connecting to them it's likely me wanting to take a break from reading your messages and fucking with you.
VPNs are great, but you you are effectively shifting the trust from your ISP (private company) to the VPN provider (private company). You trust that the VPN provider does what they say and doesn't log your activity, hides your originating IP and keeps their software up-to-date and secure.
Any website host can/will/may block VPNs to *protect* themselves. We do it to varying levels on this site and our servers; yes VPNs can provide a privacy protection to their users and most of the time it's fine, it really doesn't matter that a VPN service is used. But at the point that someone using a VPN starts to use it as a 'shield' to protect themselves so they can do "wrong"; be that activities such as spam, hate speech, racism, gore, or hacking attempts - it's at that point a host starts to block all users of the VPN or just generally the usage of VPNs.
But that's a complete aside to the original topic of this thread... but I like the topic as it interests me
