CAPTCHA
I run three blogs. None of them is wildly active. Some of the posts have received a few comments – thanks for the interest!
Until now I simply had a system in which unknown posters have to have their first post approved by me. Once I have approved a post from you, you are then able to post without further checks. This works automatically, it’s simple and easy. So far I’ve only had one human idiot whose posts I rejected.
It’s the non-human idiots that are the problem; every day I have to mark a large number of spam posts as such, and then delete them. It is to be believed that the vast majority of these – perhaps all – are machine-generated: spambots! I’ve therefore just added a “captcha” system. Most readers will be familiar with this kind of thing – you have to recognize an oddly written sequence of letters or numbers, perhaps a word. This is very hard to program a machine to do, so mostly only humans will get past.
I think I have set it so that it is only if you are an unknown user that this will appear. Like the freedom to add messages without me having to check them that known users, with a history of at least one approved comment, already have, it’s only the first time that you should have to face this small hurdle. If you have any problems with it – please let me know!
