The ads are universal across ALL boards on this platform. 8chan does not control the advertisements at the top.
It is what it is.
If you can't deal with it, then you should find somewhere you feel more secure.
I will tell you that, if you have an issue with those ads, you are not at all prepared for the TRUTHS that are about to become evident.
You need to research moar- for your own good.
Here, or there, or here.
