Probably embarrassingly high for the MLC SC.
Last I heard, they actually lose money on their presumed fundraisers, justifying such by that everyone (?) had a good time at their parties and dances. The main SC was reported to lose a million on its activities, one year.
Money that by them could have been used to hire more lobbyists or staff to urge more and better enviro laws and habits. Course, this all is non grata discussion, here!
I get paper solicitations from Defenders, email from SC. I don't know why that would be true.
Just like with e-mail, if you reply or bounce the message back, that they then infer someone is reading that, and that can mean money. If you gave to whatever organization, that info does get shared, and thus the junk mail. You can be sure that if you send even one penny, it means more cut trees, or global warming, now, for the spam to be sent and received, by some.
Though I like my own computing to be measured in milligrams of CO2
emitted, rather than in tons, as the good mentally debilitated enviro will happily do, with their mindless motoring about, doing their good for the planet (far worse rationales, there, than by me for anything I say or post!).
