I have no idea where sense 3 came from. It's not in the refs I quoted. ポッチ + opal get 6k hits, so that's a possible entry.

rm comp as suggested above, and synching with 独りぼっち.

sense 3 is not in any of my refs, but ぼっち[bocchi] is so close to "potch" in pronunciation that i wonder if it might actually be gairaigo (i.e., a typo here).  should it be in an entry ポッチ[pocchi]?

I think it needs its own entry. It's not really sense 2 of this one.

Meaning sense #2 can also be written ぽっち (一人ぽっち、二人ぽっち、三人ぽっち), but I don't know if that is true for #1 and #3, so I'm not sure if ぽっち　should be added here or have its own entry.　Also, at least in the case of ぽっち, it isn't necessarily a computer technology term.
