I used to be wholly against the idea of sponsored posts.
When I was number one on Google for terms like “best blog” and “funny blogs” I was approached a lot by companies who wanted to sponsor my posts. Most were firms of ill repute and were peddling dildos and other items of adult nature. But still, it was an offer of free money. The problem is that they all required me to do something ridiculous like put a link to their product in the ad, or write about a topic which featured their items, etc. Stuff that I don’t approve of. I have integrity, yo!
