Lemmy.world blocks VPNs

Basically the title. I use MullVad, and recently discovered that Lemmy.world is not allowing me to submit new posts or commenting on others' posts if I have my VPN on.

For now I have excluded my Lemmy client of choice (Voyager) from my VPN, so things are back to normal.

As a reason behind this, I read elsewhere that this blocking of VPN is intentional as certain people posted CSAM while behind VPN. This is pretty despicable, so I totally support shutting those people out.

However, on that same note, I think it is fair to assume that every post and comment on Lemmy is stored along with the IP address of the User. Is that right?

Edit : Some readers are confirming that they can write posts and comments in Lemmy.world while on a VPN - and I wholeheartedly thank them. I only posted what I personally (and some other lemmings as well) experienced. I still do not know if this is a widespread problem or only happening to a few.
