I get that you’ve got good intentions, but this reads like an email I would find my spam folder and I can’t imagine it would inspire any reddit mods to move over to Lemmy. The mods who were so dissatisfied with Reddit that they would be willing to migrate with the information in this script have already done so.
There are likely be some who might be willing to migrate if they get personal support from an instance admin or some other tangible offer of assistance, but nobody is going to jump ship just because “Reddit Bad” anymore.
