Revivals do not count on threads which are on a user's message wall, though users should be considerate. Remember, some people have email notifications on. Is it worth posting what you are posting and do you think the person will be okay with it?
If a user has revived a thread, be helpful. If you're going to point out that a thread has been revived, then you should also guide the users to the forum rules. The wiki's forum along with the rules can be found under the "COMMUNITY" tab. Alternatively, you may type the following as a response which will automatically guide the user:
Hi, TheOofer111! Welcome to Town of Salem Wiki and thank you for your edit or comment in the Neutral Killing Buffs page!
Would you like to help out or are you here for the community? In either case, you may want to check out the community portal to get started! If you haven't already, please also take a quick look at the Wikia Community Guidelines.
