Go to your local blacklist and remove those words by clicking the green checks to re-enable those words: http://b2evolution.net/man/local-blacklist

Your next question will likely be: how did those words get into the blacklist? it makes no sense.

Answer: during the 10 years you have had auto-updates of the central blacklist turned on, you have downloaded stuff that should never have gotten onto the central blacklist.

How di it get on the central blacklist? A: at some point, someone thought it was cool to crowdsource the blacklist. And some German dude for example would validate "article" as a spam word because "article" is not a German word...

The central blacklist goes through a much thorough review process now before sending out new blacklisted words.

Also a future version will allow us to revoke spam words like "article" which have been marked as spam somewhere in the past.

Thanks.

And yes, that would have been the next question.

Next question: is there a way to prune the system log?

Is there?

No.
