"Solicitation" has that "other" meaning you seem to be referring to here as well, Peg, but in places of business -- well, *legitimate* business

-- it means "don't bother people by pressuring them to buy something from your kid's school fund raising event or give to your favorite charity," etc.
Some of the longer-term members will recall an issue we had here several years ago with a member who caused a lot of very real IRL problems for someone else here, as well as months' worth of suspicion and lack of trust due to her misrepresentation of herself and her needs. Best advice is always to err on the side of caution.
