Post full CGs before or after? (Patreon)

There's no way to add spoilers in Patreon, so if I post a CG, everyone sees it, even if they don't want to.

Some people like seeing the process, and some people would prefer not to get spoiled. The time it takes for a CG to be finished, to actually being included in the game, is about 2 months (hence why I tend to show it earlier).

However, that does mean spoiling people earlier, so what should I do? Post the CGs before the chapter has been released, or after? And a third option I guess; I can post CGs on Discord (which has spoiler tags).
