The following are four remotely hosted comment solutions that have caught my eye.
- Commento.io - privacy focus, no ads, lots of features, Akismet anti-spam, starting at $3 per mo.
- Intense Debate - Owned by Automattic, Akismet, Lists Trackbacks and Pings in addition to comments. Silent about ads. No mention of pricing prior to signup. That always gives me pause.
- Commentbox.io - looks more basic. Talks about comment filters and blocking for antispam. No import from WP native comments. Free for under 100 comments per mo. Costs if you go over.
- Disqus - we’ve all encountered it. Has lots of import features. Don’t expect privacy. I don’t know how good their anti spam is. Might be able to get it free without ads for personal blog without ads.
