Add a SPAM filter service (via API-backend call) to the front-end site.
Use something like: http://akismet.com/development/
It’s relatively affordable.
Get the API and integrate it with your blog. Write it to only enable when the API-Key is available. Otherwise, the API should be disabled – this allows you to have the API ready for when you’re ready to pay the monthly fees…
HATE the SPAM, not the users…
Note, there is a FREE version too!Just change the annual pay to $0/yr and they will email the “FREE” API key. There are supposedly limitations on bandwidth and number of queries/month… But for starters, this is great!
