It's harder to find but it still exists. The hardest part is finding the retroscape <communities> rather than individuals/people. For example, I can browse a lot of retro-ish early 2000's design sites on Neocities but it is difficult to call it much of a community. Same thing with mmm.page.
For anyone nostalgic for this type of old/weird internet, you should check out TikTok before it becomes too commercial/formalized. Still a lot of weird/random/raw stuff on there.
