Yo, the height on Amon's page is an estimate based on his comparison (side to side) with Korra. She's 5'7", and it's not hard to ballpark how tall he is. Seeing as the word 'estimate' is right beside it, I think it should be allowed to stay.
That is now an edit war. For future reference, please don't undo an edit without leaving a reason why. In cases of you undoing an edit of someone undoing an edit, that constitutes an edit war and should be discussed prior to undoing once more. Status quo prevails in this instance, which is what the page looked like before your edit.
Sokka, Katara and Ty Lee ALL have characters that are listed as love interest in their love interest. There for, by what has already been established on other character pages Jin has every right to be listed next to Mai. In other words, Yes we DO list Love Interest.
I know that now. As in, I didn't know that before, and you did, and thus it really should have been explained the first time you undid the edit. As I said in the summary, you've been here long enough to know our rules regarding edits and edit wars. Please follow them next time.
As for the actual date, I don't believe Jin should be noted. They had one date, and while Zuko seemed interested, that doesn't mean that she was a love interest. It just means they had a good date in which the characters were interested in each other for the duration of the date. It was a passing fancy, nothing more.
Then by that Sokka should not be listed as a love interest on Ty Lee's character page since they only had one scene where they weren't fighting and that was in the series finally and by then she showed no interest in him what so ever. Every other time they meet, even the one time when Ty Lee actually flirts and Sokka shows no interest in her at all and they where still fighting.
Ty Lee showed an interest in him on more than one occasion, going so far as to openly flirt with him (again, on more than one occasion). He is very much a romantic interest to her, but it's not reciprocated.
This is not to be taken as me starting a argument, I am just going over what I know. Ty Lee only ever flirted with Sokka once in the series, The Crossroads of Destiny. Also we can infer that Zuko was at least somewhat interested in Jin, since he did enjoy the date and returned her kiss. Yes he never spoke of her again and he broke it off after the first date but that doesn't mean that he was not interested in her, even if it was only for that one moment.
Now if Song was put on Zuko's list then yes I would agree 100% that she does not qualify as a love interest since there is NOTHING in their interaction that indicates that either she or Zuko had any sort of romantic feelings for each other.
