Well, I still don't consider it cheating. I've asked Pinstar about it before and never got a response, so I decided to make my own decision.
Besides, my legacy is more focused on the story than the points (I still keep track of the points for the fun of it, but it's not my main focus of the legacy), and I needed that mod to carry out a strategy in my legacy. Plus, people who read the chapter loved it and bombarded me with positive comments, so I guess I completed my objective: to have fun and create a great, thrilling story to read.
Maybe if you're a point-n.a.z.i, the teen pregnancy mod would get your knickers in a bunch, but for people who just want to have fun and make a great story using the basic setup of the Legacy Challenge, it's a great story tool.
P. S: I do believe in following the rules, generally. Making up points for your heiress having a certain hair colour, for example, shouldn't be done, or using money cheats, etc, etc. I have followed every other rule to a tee, just the teen pregnancy mod was just too good of a story to pass up.
