Mr. Zhu,

forgive me if I'm wrong, but you appear to be advertising
a service for ripping off other people's products.
I'm trying hard to think of legitimate reasons for needing
such services, for example "whoops I've lost all my source code
and can remember so little it is quicker to crack it"
but this strains credulity.

As kids, we've all taken things apart to find out how they work
(or in most cases, how they used to work).
A healthy curiosity is a fine thing (if you're not a cat).
I personally don't mind a few curious PIC hobbyists doing this
kind of thing to satisfy curiosity or save a few bucks pocket money,
nor even fellow professionals trying to solve an obstinate bug.
In the latter case they can just ask me or other chaps on this
list for help.

However, your fees indicate you wish to do this on an industrial scale.

> We honorly provide you the decoding service
> for almost any kind of PICs!!!

The word  honour' sit on your lips as uneasily as
the word  chastity' on the lips of a whore.
You can't even spell it right.

> In case of failure, all payment is refunded
> to the customer unconditionally.

That's reassuring, from a person of your integrity.
If you have any scruples, I'll bet they don't belong to you.
You sir, are a cad, a thief, and a parasite.

May you be reverse engineered by your own
diabolical methods, you bounder!

Signed, A Gentleman.
