Personally I believe that contracts need clear break conditions and loyalty is too nebulous.
For example: the Dumbledore's Army parchment jinx triggers when one of the students tells a teacher about the meeting not simply hints at it.

i love that last one, it was genius

I love it - born "as the seventh month dies"!

Omd love it lol

I like the punch line of the last one, The Wages...

oh.. this was good..

In "Day of the Toad", I was muttering, "Hey, there's no contract if it's signed under duress".

Then, I realized that doesn't apply to Rowling's Magical Contracts (TM). Oh, how her lawyers must have mocked her behind her back.

...you can jump all you want but it's the Day of the Toad.
*snort*

And the fun thing about 'Avoiding The Contract' is it could be either Tom or Harry.

These were all good. A room full of Slytherin's will give rise to plots and betrayal. I thought you did Dumbledore's thinking perfectly, he is too sly to trust people with so much at stake.

Magical contracts are scary. Thanks for posting this.

The last was the best. LOL! Thanks for sharing

interesting.

Lol. Yeah, magically binding contracts are really too powerful to exist in canon as we know it.

I especially enjoyed Tom as a snake-handler.
