A bypass is defined as having access to some Internet resource that Plucky, as configured on the computer in question, is supposed to block. It is sometimes also called a loophole or a way around it.
Here is an example bypass.
Plucky isn’t easy to bypass, or it isn’t supposed to be. But Plucky isn’t perfect, and from time to time, bypasses have surfaced. If you have discovered a bypass, please do not post about it publicly. Instead, report the bypass discretely, privately, on the sly (nudge nudge, wink wink), because if you post about it publicly, such as on a forum, you will almost certainly be doing a disservice to other subscribers of the forum.
Thanks for considering your fellows, and happy plucking.
