Like a lot of bloggers I get hit by spam.
Blogger filters them so you readers don't see them, but I have to manually remove anonymous spam content from the spam file, my email accounts and my laptop/Iphone.
It has become a pain in the erse.
I have changed my Blogger settings as a first step in the defence against web abuse.
So regular readers you will need, at least for a while, to use word verification/captcha when you post a comment.
Sorry, but that is the way it is.
Here is the origin of the term, long before the internet was invented.
