@esaeger Hiya, and welcome to CounterSocial!
Unofficial status update:
Site slowdown/glitches are temporary and due entirely to the sudden influx of users.
Moderation team may be running behind for a little bit; the population of the site has, by my estimation, increased by several times in the last 72 hours.
If you find the interface overwhelming, go to the Settings (three dots menu near the top-left hand side -> Preferences) and turn on Ostrich mode. It calms it down significantly.
@esaeger As for far-leftists... I'm one myself! Earned yourself a follow for that one :D
