Apart from me, active right now I've met here Elliah, butterbutterfly and I think LilacGirl, for example. I've started to think about it, because I feel like the same few people who interact with me on Stray Kids' threads, I interact with/see frequently on EXO threads.
On our Michelins' discord group there's a good amount of ex-active users who either stan or used to stan EXO at some point. Probably there's more I've never interacted with.
It's just curious, because I expected more crossover here with other fandoms, since their music is vastly different, their strengths as groups are different and the dynamics/chemistry between the members is also different.
