There are pros and cons to anyplace and anytime you post online.
I find it hard to believe that any online place would object to a safe haven for those seeking help and support for recovery. I would just be cautious of the words used there, as there may be built-in algorithms that search for such words resulting in an arbitrary shut down of a server within discord without realizing what that server is actually about.
Discord is very nice in that when people chat there, responses are almost immediate (ie, no wait time, unless someone has a problem with their internet provider). It also offers voice and video options, which can be either one on one or group voice/video.
As long as you abide by the TOS/guidelines I don't think you will have a problem. And a server on discord set up as Recovery/Aid would not violate the TOS.
There are also bots that can be added for free that allow for music/games/etc., if people just want to get out of their heads a bit. Not to mention that bots can be set up to "police," the site based on predefined rules.
For those who want to check out Discord TOS, they can be found here:
https://discord.com/terms and the guidelines for their site, which are much easier to read, can be found here:
https://discord.com/guidelines
As others have said, use of a VPN or TOR (if possible), would facilitate anonymity.
I think you have a great idea
@avoid_slow_death. I think it might be very helpful to those trying to recover or trying to stay in recovery.
The powers that be here, could also add a visible link to the site, indicating that in addition to the recovery section provided here, there is an active recovery site on discord. Seems to me this would be a win-win for everyone.

On edit: I once created a server there and had no problem with it.
