Untitled (Patreon)

I have several patrons that never interact with me, never hit likes, never comment and such on.. Their reward tiers include monthly art suggestions and votes, do I really have to contact each of those guys personally to remind that they're eligible for certain rewards? I'm posting notifications here and on tumblr, that should be enough? oAo If they never react but keep pledging, I should just leave them it peace, rite? Maybe they just want to support without being rewarded, idk. o3o
