Consider changing comment handler

Currently this plugin uses preprocess_comment filter (with a priority of 10) to check the results of the captcha.

However, this is causing a great deal of API requests to end up hitting akismet (which also uses that same filter at a priority of 1).

I’m hoping you’ll consider switching to an earlier hook such as pre_comment_on_post to help save on akismet requests. Many of us use paid akismet accounts where api requests matter.

Thanks for your consideration!
