Backup
The site and all of the web apps are hosted by a single person. For this reason, I plan to back up the database and have it available for members in the case of me closing the whole operation or wanting to pass it to another person.
Leaking
Leaking of material from this site to other forums is not endorsed, for the health of the group I recommend inviting other like-minded people. But at the end of the day, it is not something that I have too strong feelings about, we do not own anything that we are buying and trading and I don’t feel I have authority there.
Privacy
The only data I keep is purchase records and contacts, none of this is ever shared with others. being completely self-hosted my end is encrypted so the level of privacy falls on the user, I recommend using encrypted mail clients such as Proton Mail.
