Thanks for dropping by my blog and taking your time to cut and paste a comment (you left the same comment on my ah ok lah blog as well). I would like to let you know that I don't really appreciate spam comments (which it was).
I did look up the service that you are talking about and it does seem like a good idea. If you are looking to promote your site or are helping to promote a site, this is definitely not the right way. You may be actually driving away potential customers. For example, a negative review from me will definitely not help.
If you want a review or want to advertise on my blogs, you are most welcome but please contact me via my email: ahoklah[at]gmail[dot]com
