Remove CAPCHA and replace with better spam protection
Removing the CAPCHA would remove the cache-unfriendly code (see #13 (closed)) and fix the problem of CAPCHAs not working in browsers (see #4 (closed))
To replace this and make the spam problem easier, it would be a good idea to implement some different measures:
- Negative (or honeypot) form CAPCHA
- Confirmation pages for comments (it also helps users fix mistakes)
- Spam filtering in comments for the remaining spam that gets through
