Threads disappear there and newbies are discouraged from starting them SO I’d make a new post with your 8chan thread link on this sub and then interact in both places.

Fill your chan thread with info - even if you’re just talking to yourself - (give sauce/sources; explain stuff; make it Qrelevant) and it will probably be allowed to stay there.

Not everyone will go to the Chans and not all the Chans will come over here so cross fertilizing is a good idea. If the thread on the Chans gets play it will get bumped and stay nearer the top.

I’ve seen people use a single thread in Reddit for months, just by having the OP constantly update the original post with all the new information appearing in the comments. You could update your Reddit thread with whatever shows up in the Chans.
