Nice way to dodge answers:
Missing files It olny needed the two it had.
Improper packaging Azjh_SizeDef Seems like a good name.
Syntax errors (ie doesn't work) Tested and worked.
Breaks game Tested and worked.
Overwrites other datablocks Um, IDK what that even means, so no.
They ported someone else's add-on and did a crappy job Nope, my idea.
Description contains the phrase "I didn't test this" or something similar Definitly didn't say that.
1. Obviously not.
2. PACKAGING is not the same as NAMING, but your add-on doesn't have a proper name either.
3. Not well enough, if it returned syntax errors.
4. Then you shouldn't be trying to make an add-on. It's very important information.
5. He never said you stole an idea.
6. Badspot doesn't lie to make your add-on stuff, it does that on its own. Nice job.
Next, improve your english. I have a vague assumption you speak another language?
Finally, what WAS the add-on in the first place? Azjh_Tiny doesn't explain anything.
