[Meta] I have a ton of saved maps to post, but I didn't create them

As a DM of many years I've collected battle maps, and I could post them here to fill the community with content. This issue is I did not make them, and I wondered how the community felt about posting them here.

Here's an idea of how to do it ethically:

1. Include their watermark (obviously)
2. Include a link to their socials (this one might he hard for me since my only socials are Mastodon and Lemmy)
3. Ask the creator for explicit consent (this one would be extremely difficult, as above. Additionally, the creator may not exist anymore.)

Any thoughts? I didn't see rules in the sidebar so I figured to just ask. Thanks!
