With 1,846 pending comments I decided to let JetPack check them all for spam – they no longer offer a free version but it’s only $3.50/month. Or so it seemed – as I was trying to sign up it seemed the only option was to subscribe yearly. I struggled to find a way to switch billing to monthly.
Solution was to click on the “trash” icon in the checkout:
…and that took me to this page that had an option to switch to monthly payments.
I still am having a hard time getting it to work so I may have updates to share on how to get an older Akismet API to process via the “Check for Spam” button in the Comments Admin. I am getting “Akismet Error Code: 10403”
update: I have an Akismet API that dates back perhaps 10 years. the API key used to be attached to many sites back when the free option was more available. So it took a lot of back and forth with support to finally get my API unblocked and sort all the spam. As usual, there were a few gems buried in the pile of spam, proving once again that Akismet works well.
