This article will describe how lemmy instance admins can purge images from pict-rs.

Nightmare on Lemmy Street (A Fediverse GDPR Horror Story)

This is (also) a horror story about accidentally uploading very sensitive data to Lemmy, and the (surprisingly) difficult task of deleting it.

I know that the fediverser project is quite a bit controversial due to the mirroring bots and how they were being used on alien.top, but today I'd like to talk about two other pieces of functionality which I believe have been ignored and eclipsed by the mirrors:

• The ability for users to signup to the lemmy instance by connecting via their Reddit account.
• The ability for instance admins to create a custom map of subreddit-to-lemmy communities, which can be used to auto-subscribe users who are registering via Reddit.

I think that these two pieces can really help solve the problem of user onboarding. Because it works as an extra service along with Lemmy, no changes in the core service are needed. For users, the possibility of starting an account on Lemmy and get a list of interesting content right away can reduce friction and would hopefully get more people to talk about it.

I'm particularly interested in hearing from the admins of the topic-focused instances, as (I believe) would have an easier way to reach out to the people that are closer to their interests. So, apologies in advance for the mass-tagging, here are the ones that I found on join-lemmy:

To reiterate, this has nothing to do with the bots or mirrors deployed on alien.top. I'm only asking who would be interested in adding the functionality to allow user registration via Reddit OAuth. In case of any questions, feel free to ask here or reach out via matrix.

Most of the top 500 subreddits (by subscriber count) are fully mapped to the corresponding Lemmy community.

I've also ran a script to identify all the "over 18" subreddits that have a corresponding community on lemmynsfw, and linked them. This resulted in almost 700 communities.

In the following days, I'd like to find specific niches that need to be categorized and then see if any of the topic-specific instances would be interested in creating the communities that are missing.

I just found out about mander.xyz and it seems like a solid alternative for a science-focused instance. Can we go through its list of communities and map to the corresponding subreddits?

When building out the database of recommended Lemmy communities, I think it makes the most sense to prioritize the communities that belong to instances focused on a specific topic over communities that are based in a "general" instance, even if currently the community is smaller in the topic-specific instance.

For example, for an user coming from reddit and signing up via a "fediversed" instance (like alien.top) it would make more sense if they see that the anime subreddits are on ani.social, the rpg/board games are on ttrpg.network, the programming communities are on programming.dev, the basketball ones are on nba.space, the NSFW communities are on lemmynsfw, etc, etc...

This will also avoid the issue that I am currently seeing where some communities have multiple entries in the recommended database due to the initial migration where each user was just trying to replicate their favorite subreddits in their own server they signed up for.
