Can't really do much about it, all you can do is tolerate it.
install ad blocker
That happened to me, too a week ago or so. I installed an add blocker and everything's back to normal now.
Is there one you guys recommend?
Do you have one you recommend?
Mine's called addblock plus but I don't know if it's high quality or anything. Just googled addblocks and chose one that seemed compatible.
I use two - one is simply called AdBlock (for Chrome) the other is Fair AdBlock (by Stands) - have yet to see an ad/pop-up or get redirected ...
I'm getting a lot of pop up websites when I click on the manga, but I have an account. Does anyone know what the problem is?
