Only community train organizers are allowed to leak links from giveaway providers.

Blacklisted: If you come across a cart that has been blacklisted by the creator, use a different browser that is not logged into Steamgifts (or log off this browser) to view the GA and get the link to the next cart, or use the previous GA to get the link. If you ask, someone with good intentions should be able to give you the link. Alternatively, right-click on the link to the cart that has been blacklisted by the creator and select "Open in new private window" (or "Open link in new incognito window" for chrome).

The rules for the community train are as described in the description.

If you ask, someone with good intentions should be able to give you the link.

It seems to me that people with good intentions should inherently need to "get consent" for links.
We are talking about the fact that these could be problems in the future.
