I am writing to tell you that I have turned on comment moderation but only for comments that are 8+ days older than the post. We have been spammed lately . . . and all the junk has been on comments that are way older than one week. This has happened on my own blogs and I found that turning on comment moderation for older posts has stopped it.
This should not be too inconvenient for us. Of course, I will approve any valid comment (it is so easy to tell the difference!) and I receive notification instantly.
I hope you are all having a wonderful summer day without rain or troubles.
