Lets be honest, the Marvel community is as good at keeping secrets as the Game of Thrones fanbase; especially when people asked who Gwen Stacy was and the fan response was "Spider-Mans dead girlfriend". If you really want to enjoy the film, avoid all the on-set photos, ignore the rumours, do not read any of the reviews, and its probably best if you sign out of Facebook for a few days. For anyone who does see it early, its best you abide by the one week rule. WhatCulture will do its hardest to make sure it doesnt ruin the viewing for anyone too. Its a common courtesy.
