When you go online, there is no way you escape from these two things, comments & spams.
Honestly speaking, I see comments as something that build me. I believe when you are dare enough to write your ideas online, you have to be ready to be hated or supported. There is no way everyone agree with your ideas or suggestions. So, I really appreciate all comments and suggestions from all the readers. People comment because they are considering and challenging your ideas.
Most of the time, spam is something that is very annoying. However, I do not really affected by them directly, because I usually turn all email notifications off. For Wordpress, I will try to skim through all messages (spam) before actually taking more time reading them.
I will keep learning and finding better strategies, as I use this website more often.. (:
