I understand the need for marketing companies to promote the message of their clients, but it appears that some of your methods are ones considered socially unacceptable and irresponsible to others that have to share the internet with you.
Plastering your message across sites frequented by others without thought for others using the site is annoying, and I was disappointed by you eagerness to do so repeatedly here and on other sites. Others may feel that these activities are a reality of the internet today, but I feel that sites should not be required to block specific IP addresses just so that they are able to provide regular services to their users.
Personally such behaviour makes me angry and not positively disposed towards any of you clients, which I have declined to name here. To me the reality of the internet is that this type of behaviour will continue while there are companies prepared to make use of these services, and I look forward to the day companies choose their marketing needs with greater care.
