That certainly used to be the case pre-2012. All the former hactivists have long since left. marriage, kids, real life, etc... Now it's mostly handfuls of edgy boys on cell phones in school and 4chan-GPT creating and responding to threads. I wish I were wrong. The site went mostly dead for about two weeks when USAID was defunded and had to shift funding sources then all the usual re-re-re-re-re-posted topics in /g/ returned. Some of them are on this site too ... inb4 they reply. Adding to this now the general public have the real names, IP addresses and locations of all the moderators so they are less likely to participate in doxxing.
There was a quote, "4chan is where smart people go to act stupid, facebook/reddit is where stupid people go to act smart". That probably needs to be updated.
