I am not a staff member, but I am a member of Kaimittee Legal Services which qualifies me to respond.

1) No.
2) NPCScript? Yes. Use external scripts to do something for you or otherwise effect the Graal executable, no.
3) Questionable. Whether or not this is a violation centers around whether or not a true benefit is derived from glitching (in which case it is bug abuse) or if it is neutral/negative to the player (in which case it is bug use).
4) Yes
5) No
6) Yes
7) No
8) A gray area.
9) Probably not.
10) No. You aren't supposed to be able to pick up items in another person's house so this constitutes bug abuse.
11) No, see 10.
12) No.
13) No.
14) No.
15) No.
16) Probably not.
17) Probably not.
18) Probably not.
19) Yes.
20) Yes.
21) Probably not. The fact that staff seem to return PKed amulets suggests that dropping them might be a bug (therefore PKing amulets is bug abuse).

35) No, probably and gray area.
36) No.
37) It seems so (unless it violates external laws) but I'm really not sure on this one.
38) Technicly yes so long as it doesn't violate external laws.
39) Technicly yes so long as it doesn't violate external laws.
40) Technicly yes so long as it doesn't violate external laws.
41) Probably.
42) Probably not.
43) No.
44) Yes.
