[Enhancement] Notify User When Search Query is Deemed Innapropriate by Tumblr

[Binzy-Boi]

When a user submits certain search queries on Tumblr, Tumblr will give a message stating that they won't fetch results as said results may break the site's User Guidelines.

As an example, searching for "pr0n" gives the following as a message:

While Priviblur predictably shows no search results for the same search query, the page simply appears as blank, which may confuse the end user into believing that the frontend failed to fetch results when in reality, the search results were never provided to the frontend by Tumblr.

(Unrelated to the issue above, but gonna use this opportunity to ask if a Codeberg mirror is possible seeing that I'm trying to avoid GitHub whenever possible and would love to contribute to Priviblur there)

While I'm not opposed to a mirror on a platform other than Github, I think a mirror that allows for contributions will increase the maintenance burden of Priviblur by quite a bit due to:

1. The need to triage issues on both platforms to remove duplicates and/or to mirror the issue on the other platform
2. The workflow for closing all corresponding issues when a problem is fixed on both platforms
3. The synchronization of the two mirrors

etc.

And personally speaking I don't think I have the time to attend to two repos. Perhaps in the future when and if Priviblur becomes a larger project with multiple maintainers, a mirror that also allows for contributions would be possible though for now I'll be sticking with just GitHub.
