Spinners On The Net

For knavish gain they spin
Manifold lies and stories
All borne by Greed within
Sly charlatans are these.

Spinners on the net
Weave very crafty video
Obviously to get
Donations, that is so!

Beware and check them out
Although the cause be noble
Probe what it's all about
Lest you heed a spinner's call.
