Then after finishing my writing when I wanted to make a post Cloudflare hanged me up for over ten minutes. The 5 seconds were never ending over ten minutes.
Usually i could solve the problem by changing circuit ("New Tor Circuit for this site") few times.
As for the problems while posting I guess theymos can have tweaks if this is common to TOR users.
AFAIK theymos already configured CloudFlare to allow Tor users. For comparison, some website which use cloudflare simply configure it to deny Tor user.
