[killing the dream]

I did a quick search and couldn't find anything that answered this.

I had a question about this series.
As I've heard there is a lot of filler going on right now to let the manga story progress enough.
here are my questions.

A) is the filler on a random episode basis, squished in between actual story line episodes?

B) or are there filler arcs with 30-40 fillers in a row?

My reason for these questions are that if I were to start watching the series I would like to skip as much filler as possible. So if this series pertains more to scenario B, it would be easier to skip an arc at a time.

Lastly, is there a list or guide anywhere that shows which eps are filler and which aren't?
(ex:ep1-35 is storyline, 36-50 is filler, 51-80 is storyline ect......)

thank you
