I switched off word verification a few days ago because those blurry words and fuzzy numbers are not always easy to read. This was potentially off-putting for readers who might want to contribute to the discussions but have difficulty making out those figures.
But then the spamming started in earnest.
I was happy to leave verification off because I thought that I was the only one who was going to see the spam. Blogger's filter catches a lot of it before it's published and I try to bin the rest as soon as I see it. What I didn't realise was that everyone who has subscribed to the comments also gets hit by the spam. I can't have that. That's just rude. So sorry to everyone who ended up with that rubbish in their inboxes. It's not fair that you get spammed as well.
I've now reinstated word verification. I hope that those of you who struggle with the images aren't put off commenting. My apologies to you, too.
