Reputations are just history in rumor form, you can change it.
Rumors, they can do very bad things in relationships and our communities. Spreading misinformation can wreck reputations of good people and advance the agenda of bad people. The old saying loose lips sink ships is so timeless. Be careful with information, it can come back to bite you.
Sometimes I shake my head when I am on Facebook. People buy into stuff that isn’t true because it fits their limited world view. Rumors can spread like wildfire there. Of course every social network including Tumblr have folks who advance information that isn’t true. That’s when you gotta look elsewhere on the web for further information or even go off line.
