There will always be a way to filter spam comments, well at least most of them. You even pointed out that automated spam is predictable.
As for the link love (I like this term) you are correct. A good way to avoid this is to approve email addresses on their first post. Correct me if I am wrong but I remember you having to approve my email address after my first comment on here. This is, to my opinion, a very good approach and I have mimicked it to my blog.
Other than that, I havena€?t ever spotted a spam comment on here. Was wondering, how much time do you spent handling spam comments?f2富二代官网入口
