When commenting, get "Please slow down, you are posting to[sic] fast"

Wow, is nobody else ever seeing this?

I’m seeing this on a site that uses “spam free wordpress”. I’m starting to hate that plugin’s guts, incidentally; it claims I mistyped its captcha about dozens of times, and now that it doesn’t, I’m posting to[] fast.

For what it’s worth, I have come up with an anti-spam solution that has stopped ALL but a couple of spams from getting through. No Akismet, no spam folder to look through EVER, and only 2 plugins needed:

G.A.S.P. (Growmap Anti Spambot Plugin)
Spammer Blocker

With these two enabled, I get zero automated spam, and the rare human-submitted spam that makes it through, requires just one click to ban that spammer’s IP.

This has become my automatic go-to for every blog I install, in terms of stopping all spam dead in its tracks.

Oh but to respond to the original topic… I never did get a satisfactory answer to what was causing it in my case, but it also seemed to go away on its own…
