My altered name is lurking slyly here
As my self-referential words make clear.
You've guessed my easy riddle now, I fear.
The title could have been: "My 25% Odds Acrostic Riddle"
https://www.google.ch/webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=acrostic In this case, I used another marker
Hinting again, and summarizing clues from comments
One piece of punctuation was a misdirection
All parts of the puzzle (everything above "A hint:") are significant
This is not a usual acrostic. The title is a key or map to the solution
The "My" in the title is a clue that the word "my" is the acrostic marker
3 2 1 is not an ordering and the digits may mean different things
There is always a trick
The word "self-referential" applies in more than one way here
There is a certain tricky sense in which this puzzle is indeed easy
Want something specific?
There are six letters in the solution.
