Agreed.

But if you are in a specialised field, like myself, little spamming can have an great effect in the ranking. But also someone has to actually click on it.

I tried a bit. But since my comments did not get removed, i guess the original poster is ok with it.

You have to keep trying new things. What works today is not working tomorrow.

Especially if it is annoying people it cant be good marketing. It is always best to try to add real value. If people can appreciate your effort they will appreciate your product.
