Oh god! Isn't it a way too public?

I'd restrict it for logged users only.
The bug with no method 'abs' seems gone.
i do also think this is too public. for example i can send an amount to an btc address and write some totally different in the note maybe to influence someone. as receiver do i have the option to delete the info?
That is the point, for it to be PUBLIC NOTES. This could be used for things such as the example piuk gave, thefts, etc.
