I had enable comment moderation on this blog due to reason below.
Lately this blog been getting this kind of comment posting from various (suspected same) people with this sentence and redirect to an aquaponics site that selling things.
This must be a robot or something all 22 comments are from this single person today after I enable comments moderation.
I had enable moderation to this blog, since the spam still happening and I will recieve email notification of any new comment. So I will not missed any - that a good thing.
