There is no "one size fits all" method that will protect your comments, spammers use many tactics. Consider using multiple defenses(Topics) and some shits answer to your topic. Remember spammers change the way they post like seal.
I'm really not sure whether you're trying to be ironic or not, but your post makes little sense and is exactly what the op of this thread is talking about
. I'd just lock this topic because it just encourages more spam.
