Do you think mass posting across multiple subs to pub a game is too pushy ?

Basicly, ill soon get my game's steampage and i was thinking on how to get wishlists. Do you think that doing pub post telling about the game, the dev process and posting the same post to a dozen relevant sub would be too pushy ? How would you feel if u saw a post about a cool game, checked the profile and saw the same post was posted 10 times ? would that cool you off ?
