We will see what happens to gurochan going forward. I would also advise everybody to download what they haven't already, I hope they leave the old stuff alone but it's possible it could go away any time. Of course it's just as possible they find a new host and everything goes back to normal, but even if that happens it might take a long time, probably several months.

About other options:
I think it might be possible to post uncensored work on Mypixiv, some artists are certainly doing that. But no idea if it's actually allowed or just a little more tolerated - some artists are posting uncensored pics in the open without any problems too.

I still think lolicit is the best option, and you would actually get something out of it yourself, I'm sure you would enjoy some of the content there even if it's not as extreme as your own. Not to mention the option to discuss technical aspects with other artists.

For anybody who wants to give it a try:
You need to become a full member to see the boards with art in it. As a newbie when you register an account you can only see a few discussion boards, most importantly the lolicon discussion board. While not really encouraged, it's allowed to post some art in the lolicon discussion board, but just softcore stuff - no penetration and certainly no guro either.
To become a full member, you need two things:
1. 20 posts. That shouldn't be that hard for most people and it's not really what I would focus on.
2. 45 reputation points. Those are given out by other members for your posts if those members think the post deserves it. One member can give you at most 15 points, and that's for the most active members, many can't give that much (I'm at 8, and I will usually try very hard to find a reason to rep any new guro fan I can find, I want more guro fans over there).
To get the points will take time and effort. Drabok as an artist could just post some pictures in the lolicon discussion board, for example the current interlude would be completely fine there, or the introduction to the summer camp. From experience I'm confident it would be very easy for him to get the points that way and it would take him longer to get to 20 posts.
For everybody else it will be harder to get the rep points. Some people just make 50+ low effort posts and hope something sticks, but I think it's better to be smart about what you post. There are lots of threads where you could post a little fantasy or anything else that's constructive - just something that actually makes some people want to reward you for the post. The advice many people give is usually: Don't worry about the rep, just try to join the discussions and it will come.

Bobuzi, I don't think there is any reason to believe the admins would be opposed to Drabok's art. You have posted lots of it already, and there have been a few other contributors of hard guro, most recently Acid Bark. It's just that there aren't that many guro fans, and most of the less extreme stuff is going into the normal 3D section (for example Krogue's work, that has been requested on gurochan a few times - and even some of your own work could count as guro by some definitions).
