I know that the ask VOS thread is probably the best place for this, but since I'm a new member it won't let me post any replies in there.
1- are BS filters reversible? Meaning, is there any difference if it is attached to the wall plate or the back of the stb.
2- on an 8 way green label splitter with 5 of the ports being used, is there any advantage to terminating at the splitter as opposed to connecting three other cables and terminating them at their wall plates?

1. BSF are DIRECTIONAL

2. No difference

I'll have to go look, but BSFs aren't directional unless the Coax connectors demand it.

They are, there was a thread about this not along ago.  there is a reason DirecTV includes the pig tail on BSFs

Thank you. I would have done a search, but that also seems to be unavailable for new members.

Wait, if they're directional then that would mean if a BSF was attached to the wall plate, then that box could see the rest of the system, but no other boxes could access that DVR. I understand that this could also be accomplished by turning off sharing, but its an interesting thought.

Back in 2010, VOS testified that BSF were NOT directional.
 

The only "directional" part is the connectors, The filter itself doesn't care and works either way.

IIRC, they need to be unidirectional or the tank will gobble signal from the DECA side of the connection otherwise. I remember this because Comcast gave me a free month of broadband service because their subcontractor inserted my neighbor's DOCSIS filter backwards and my modem wouldn't work.

Well when I tried a search it told me that I wasn't allowed to use the search function.
*shrug* its working now.

Nope,

They're a passive filter and work  in either direction.

I've mounted them either way "as needed"/

It seems more likely that the subcontractor added the filter on the wrong drop.

 

I can't think of any passive filter that is directional.

I'll repeat my answer from post #3.

I thought that when this talk of the DECA BSF being directional got started awhile back.

 

I've met with a lot of various band stop or band reject filters over the years, and none were ever directional.
