I always advise people stick to the last trusted version and direct them to this thread:
Sticky: BearShare has been sabotaged.

You may not have the source code, but any of these 4.0 - 5.2 versions of BearShare
give you far more information about what's really going on than all the other
servents combined, which is why it is the one to use when weeding through
thickets of fake files and search pollution to get what you really want.
