I have been fighting a losing battle with spam here on Lingwë for the last couple of years. Originally, I wanted to allow anyone to comment, even anonymously, with no obstacles to avoid or hoops to jump through. That worked for a while, but eventually I started to get enough anonymous spam that I decided to require people to be registered somewhere and to have logged in. That solved the problem for quite a while too, though it did inconvenience a few regular readers. I am pretty firmly against captchas. I hate them myself, so I never wanted to inflict them on anyone. So, this was the state of things until this year.
But now, thanks to Google+, which I must say is one of the most annoying and pushy social media efforts I have ever seen, I have a new problem. Well, not that new, really. I've been putting up with it for most of a year. These spammers are registered with Google+, and so they evade that obstacle I placed on commenting: being registered and logged in somewhere. A number of people (or bots) have been repeatedly spamming Lingwë from their Google+ accounts, always Google+ — especially one pathetic jackass, Brad Maddox; just take a look at his Google+ page for spam, spam, spam, and nothing but spam! — and Google has done absolutely nothing in response to my repeated complaints. In fact, Google+ used to have a conspicuous link to report offenders, but it has either removed or hidden it. One can only guess why. Shame on you, Google. As if the YouTube/Google+ commenting debacle weren't bad enough press.
Anyway, I have finally had to enable comment moderation. I didn't want to do this, because it puts a burden on me of approving every single comment, even the legitimate ones, and this will introduce some latency into discussions. In exchange, though, I have re-enabled anonymous comments. You are now welcome to comment anonymously if you wish — though I still prefer to know who you are, unless you have a good reason to remain secretive about that — and in all cases, I'll be approving comments, and rejecting the garbage. Still no captchas, though. You're welcome! :)
Maybe these spammers will realize their comments are now going nowhere and give up. Though I doubt it. Professional spammers tend to be some of the dullest dullards ever spawned. I think you could hit one over the head with a frying pan each time he spam-commented, and he still wouldn't make the connection.
