I voted that it's fine to encourage others to find bugs, BUT not so they can just give them to someone else instead of reporting them. If you want to give them a reward for finding the bug, go ahead, but don't reward them so that you can (ab)use it, figure it out yourself (and, of course, report it).
In the second poll, I voted that no, it shouldn't be shared. If someone can't find a bug in the first place, why should they just have it given to them? More importantly, imagine if someone found a way to increase attack by huge amounts. What would happen if they shared it? Very unbalanced fighting, and more work for Mur with resetting stats. In the end, it's just a big mess that doesn't make anyone happy.
