Just got an email asking if they could publish sponsored posts on my CTF writeups blog (mushroom.cat)

Quick question for the infosec community: Do you accept sponsored content on your technical/security blogs?

And for readers: would sponsored posts on CTF writeups blogs bother you or affect how you view the content?

I'm leaning towards keeping it pure writeups, but curious what others think. Does anyone actually monetize their CTF blogs without losing credibility?
