Do not join this campaign, I was just speaking with the admin of the site to confirm my suspicions.
If you join the campaign you're risking having negative feedback applied to your account for advertising a scam.
I don't think this is a good idea. I agree that the obvious scam is obvious, however having users advertise the site is not going to make it any less obvious. It will however allow for the OP to have it's funds dwindled down and given to members of the community.
If the OP's ability to advertise via signature campaigns then he can advertise via other means that would not disburse funds into the community and would probably be more effective (likely forum advertising).
Additionally people who investor in these kinds of sites know very well the risks of investing and are essentially betting they can withdraw their money prior to the owners of the site running away with customer money
EDIT: it would probably be much more effective to give negative trust to anyone wearing LTCgear signature, which is clearly a scam but they are doing a better job of hiding as such
