It's New Year's day 2017 and I'm checking my blog for post comments
I added the functionality for visitors to add comments on posts as a way to open communication. What did I get, a load of spam by someone who didn't care about communicating but just wanted to force their crap onto my blog. Just so happens that I'd written validation, moderation and CRUD to the comments. I know, I should have expected a little spam but this individual spammed then returned and did it again.
