What lblume and nicce said, with the addition of it being both a Chinese-controlled privacy nightmare (with it apparently requiring non VOIP phone numbers for verification after being logged in for a while), as well as it making the bar to entry for cretins close to zero, meaning you'll soon find whatever chatroom you set up a prime example of Eternal September.
It is simply inaccessible to anyone not using the platform. You need to create an account and join the community/"server" to see anything posted there. You cannot find anything by using a search engine and are completely unable to export anything for local use.
Think it as software which is designed for chatting NOW. Threads, pins and whatever are just treating the symptoms instead of fixing the actual problem, where you need organised and searchable knowledge library instead of platform which was designed for interaction with memes.
