Some might choose for write.as for privacy from GAFA’s, and have scalpel style firewalls to boot.
Here are the domains and subdomains you need to enable for write.as to work.
domains:
remark.as
writeas.org
snapas.net
writeas.xyz
snap.as
writeas.net
subdomains:
write.as
tiny.write.as
howto.write.as
Then you can block if you so wish:
analytics.write.as
stats.write.as
Hope it helps!
