Tread carefully with this one. There are rules of journalism and laws that apply.
1. If you have actual evidence of wrong doing, generally they can be published as fact as long as you use the evidence in your article to back up your claims.
2. If the person is a public figure, and if you can prove that person is directly responsible for the actions, that can be published as fact.
3. In general, it is advisable to steer clear of publishing personal addresses. THere are too many problems attached. Company addresses are a different matter, because those are considered public information, unlike a personal home address.
4 If the information you have cannot be backed with publicly available evidence, or if your evidence is either shaky or coming from a less than reputable source, then you have two choices. (a) don't publish anything about this claim, or (b) word the claim as an opinion. Opinions (I believe..., I feel that..., he allegedly...,) may allow you to squeak by.
Check the libel laws for your state before doing anything. Also check with the HubPages powers that be for clarification as to what they will allow you to publish. If you can't publish it here, you may be able to publish it with some local newspapers as a freelance piece or as an op/ed piece. Do your homework first. It'll keep you out of trouble.
