Help Stop the madness!
1) Check out bulletins BEFORE reposting them.
www.snopes.com
2) Post a comment in a Bulletin with a link showing it is a hoax so others won't repost it.
What kind of posts to look for?
1) Amber alerts are HUGE! Quite often if they were true they tend to be outdated. Enough of these outdated or hoax ones cross a persons path and they may ignore a REAL one. That alone is reason enough to stop it. If you post an AMBER ALERT I suggest putting a full date down of when Child went missing (including year). Most I have seen just have "last Saturday" or "2 days ago" or "hours", some have month and day but seldome have year. The last I have found tend to be several years old.
2) Virus hoax's are quite easy to check, Snopes or
one of the other Virus protection software big guys have pretty up to date info.
3) Online petitions: Sadly even when these are true the petition is usually worthless. The following link shows why.

4) There are LOTS of other possibilities too many to mention here. I am going to keep track of the different ones that come my way in my blog section. Just for fun.
