While monitoring my Pi-Hole logs today, I noticed a bunch of queries for XXXXXX.bodis.com, where XXXXXX are numbers. I saw a few variations for the numbers, each one being queried several times.

Digging further, I found out these queries were caused by CNAME records on domains that look like they used to point to Lemmy/Kbin instances.

From what I understand, domain owners can register a CNAME record to XXXXXX.bodis.com and earn some money from the traffic it receives. I guess that each number variation is a domain owner ID in Bodis’ database. I saw between 5 to 10 different number variations, each one being pointed to by a bunch of old Lemmy domains.

This probably means that among actors who snatch expired domains, several of them have taken a specific interest with expired domains of old Lemmy instances. Another hypothesis is that there were a lot of domains registered for hosting Lemmy during the Reddit API debacle (about 1 year ago), which started expiring recently.

Are there any other instance admins who noticed the same thing ? Is any of my two hypothesis more plausible than the other ? Should we worry about this trend ?

Anyway, I hope this at least serves as a reminder to not let our domains expire ;)

    I feel like this could be abused by a bad actor by recreating instances in several ways:

    1. Use the “dead” accounts that are still mods on communities on other instances.
    2. Sneakily monitor user behavior (like votes etc.) without looking out of place.
    3. Impersonate users.

    I feel like it would be a good idea to start a list of the domains of dead instances and add them to a blocklist until the original people start using them again.

      This is just the domain name, not the instance itself. If the instance is offline the moderator accounts will be inaccessible even if the domain name is sold.

        Yes, but what if someone just creates a new instance and adds previous accounts. How do other instances know that the running instance has changed and didn’t just go offline if it’s registered on the original domain?
