It's not safer, just more inconvenient which isn't going to stop some horny kid. It also won't stop microsoft from giving this "new" "team" another round unless they never release the mod publicly OR privately. Schnurri got in trouble for getting too big at the wrong time, when microsoft decided to go on a crusade to sanitize their daycare game. The same thing is going to happen here unless the "fall guy" and all hosted content is located in china or some third world country. Another adult mod for the bedrock edition got taken down around the same time too and the creator of that mod has been missing ever since russia invaded ukraine, if a likely dead mans outdated mod got taken down do you really think age verification on discord of all places is going to prevent anything?
Moreover, all of this posturing only further harms your cause. If you really wanted the mod to have a chance you would not open a discord, not open a website, and not publicly "hand the code" over to a chick that, from a glance at her twitter, appears to be a camgirl with an unusual obsession with children's video games. Instead, you would release the updates via vpn and/or proxy from multiple sources, further obfuscating the source but that doesn't get clout, upvotes, or money so it will never happen like that.
