Comment on the question:
I have been receiving large quantities of spam through this comment fonctionality, which is particularily dumb from the spammers since nobody but me ever gets to see the comments in question, and I am interested neither in porn nor gambling websites.
As a result, I am forced to add a verification process. Please answer the question below to prove you are not a spamming bot:
What is the capital of Japan?
