Oh yeah, that is uncool. With a campaign of any kind, the board should be aware and supportive. Currently you could have 2 or more people soliciting the same person at the same time which is not a good look.
Also, I don’t think volunteers should be soliciting board members, unless possibly they are Chair of the Fundraising committee or something. Board members should be doing peer-to-peer fundraising.
Sounds like the group could use a refresher in governance and compliance.
