I don't think there is a /craft/cord. I never saw any information about it, perhaps there's a group or two that MIGHT use it but i never saw any messages about something like this, they might be very secretive about it. As long as they only use it for Soycraft purposes i don't think it is an issue. I'd see it as an issue if those groups would be inviting nusoicacas into some bigger cords' but i don't think that is the case if these cords / groups even exist.
The frootcord leaks happened, yes the staff used DER CORD' to talk. But so did the staff team use telegram, irc, etc. The problem with DER CORD lies within the majority userbase of pedocommietroons / edgyrightcuckednazilarperfaggotgroypers. This cord was only used to, as you might guess... Talk about the moderation, but also as you can see from the leaks just talking with other mods and sperging about splinters / the state of the sharty, etc. You can check the leaks and see how everything worked. Froot has said the exact same thing and i believe that is good diplomacy, transparency is key.
And CobsonTALKS... Im not sure? I checked his profiles and i don't see anything related to a cord so i suppose that's heckin fake or something.
And well as for the "normal" question, i do believe that as long as soyteens don't make any cord' that is sharty related / don't involve their discord bullshittery with the sharty it is okay, people shouldn't be mentioning it. I am sure that atleast 75% of the sharty has atleast some sort of cord' account. The issue arises when people deliberately attempt to force their shit using discord groups onto the sharty. Or when these edgyrightcuckednazilarperfaggotgroypers try to advertise their cords' on the sharty (this never works btw)
Discord as a whole and this topic should just be ignored, who cares about some random 100 member discord, jannies should sweep these faggots up and teens' should be actively trying to report advertisements / sage them and just keep on jakking' ...
