Bad Behavior Plugin Causing Lag

Hi there. Until about a month ago, I was using Bad Behavior with no problem. Now my dashboard takes a good 30 seconds to load, commenting lags, publishing lags, and deleting/approving moderated comments also lags. Pretty much everything lags. At first I thought it was my hosting company’s problem, then I disabled and re-enabled each plugin individually, and lo and behold, the problem only existed when I had BB enabled.

After reading comments on the BB site, it appears others are having the same issue.

Any thoughts? Is there an equivalent to Bad Behavior? Unfortunately, every time I disable it, my host takes my site down because of the onslaught of spam, so that’s not an option.

Thanks!

Hilary
