Thanks for including #travelfeed! About the photos, although we love them, we don't require original photos, but we require sourcing and respect of copyright when using external media. These are the same rules that bloggers have to respect if they have their own blog and don't want to get sued for copyright violation.
E.g. using a photo from Wikipedia or Pixabay/Unsplash is fine as long as the source is attributed (we also ask for that for CC0 photos, even though there it is not a license requirement), but pasting the first result from Google images, probably violating the copyright of the photographer, is not. The same goes for any kind of external media or text.
All posts in #travelfeed are also included in the TravelFeed dApp where even old posts can be discovered by a large audience of travellers, another reason to post high-quality travel content in #travelfeed :)
