You need proof of something when you accuse them. 

So that you aren't accused of falsifying that you posted ...

I have 2 witnesses that can testify that I did not have mold in my addict.

In PA you need a witness to hand serve someone.

That could be done with tracking of some kind, or if the process server had a witness with them, maybe. 

It is truly sad to see this type of accusation.

An inspection (with a 3rd party witness) is probably in your best interests.

I didn't accuse anyone with abuse or user damages.I have tried to be transparent about the issue, explaining I have been threaten with fines for doing work, service call fees are double/triple the costs, and it just comes down to, its cheaper to buy a new dryer ($475)To add to the issue, I have a 3rd year law student and the other unit is some 24 year old that works at a Big 4 Firm who think/view this is an unimaginable inconvenience, and the law student is citing all sorts of legal codes on why blah blah blah is a certain way, but obvious has never been to small claims courts where paperwork and circumstances matter greatly, or the costs of having to deal with the this stuff is problematic.

As long as you always follow this policy to the letter, there is no room for a violation (or even an accusation of a violation).

If he was going through a divorce, his ex could have accused him of something to get custody of the kids.
