Hoping I can correct a few misconceptions in your article.

You wrote, “If someone marks your comments as spam multiple times, your comments will start disappearing from many other blogs using Akismet. … someone can intentionally mark you as a spammer and you will be blocked across many blog thus limiting your social interaction”

This is not the case. Akismet learns individually for each user. If someone marks your comment as spam, that will only affect your ability to comment on that person’s blog in future. It has no direct effect on other blogs you might comment on.

Also, “Contacting Akismet team is not the best option as most of the mails are not responded to.”

We respond to all genuine questions and requests sent with our contact form:

And finally, “It does not learn” – Akismet does learn, provided everything is working properly. Most reports of problems turn out to be caused by misconfigured blog servers or confusion due to multiple spam filters. If you do think something is broken, please use the contact form linked above – we’ll do our best to help.

Your suggestions about “How to avoid being caught” are mostly good, but not because of Akismet. It’s a good idea to avoid using short comments, gratuitous links and so on because those are the things spammers commonly do. If you behave like a spammer, people will respond accordingly — and that’s true regardless of what spam filter they use, or even if they moderate comments by hand.

I hope this helps shed some light.
