Quoting from their notice:

The Vampirefreaks Social Network is officially laid to rest. We had an amazing 20+ year run and I'll be forever grateful for the experience. To the many people who have reached out to us and expressed their gratitude and shared their VF stories - it really means a lot.
I'll always remember the VF social network as a community for freaks and outcasts to be themselves and support eachother and being weirdos together.
These past few days have been really emotional and i've shed quite a few tears about it. It's been so great seeing everyone come together the final days for one last hurrah. VF touched so many people's lives and I know I can't take credit what it became, it was an accumulation of all the members worldwide who made this place their home. I started VF as just a fun project for myself and it snowballed into something bigger than I ever imagined.
The goal of VF was to create an open forum for like-minded individuals to come together. We had something special at just the right time with just the right members and it was really magical for awhile, something that we simply can't replicate in these times.
And we had a really good run for years, and I'll always be proud of that. I'm shutting down the VF social networking site for a number of reasons. It's just been a steady decline over the years and honestly it's my own fault, I could have done better. I could have kept putting countless hours every day into it but it just stopped being fun after a while when there started being a certain level of negativity from some users. We've had to deal with trolls, haters, ddos attacks, hackers, ridiculous rumors, drama and stress. We survived it all and stuck together for years and I am eternally grateful to all the supporters. There's lots of things I could have done differently but when it comes down to it, I'm proud of what we accomplished.
