Iā€™ve been very honest about this aspect of my work since the beginning: I donā€™t run any ADS, I donā€™t require subscriptions, paid or otherwise, I donā€™t collect IPs, emails, and I donā€™t have any referral links from Amazon or other merchants. I also donā€™t have any POP-UPs or COOKIES. I have repeatedly been told over the years how much I have contributed to the community.
