Should i add an aspect ratio tag to a picture that is not exacly that aspect ratio?

I'd say no. I wouldn't even bother to explicitly tag an aspect ratio, since there's a bot that automatically adds one to uploads.

I seem to remember seeing a user who got banned for putting aspect ratio tags on nearly correct images, though I can't find the record. So vote no.

Edit: As DubsTheFox says, it was user #319419. As bitWolfy says, they were told to stop and didn't.

I don't think someone tagging aspect ratios incorrectly would get banned, unless they were told to stop and they didn't.
But yes, those tags are for exact ratios only. There's a ratio metatag for non-exact matches – see the cheatsheet for more info.

I'd like to ask you about it because just saw Feedback related to it, and I am curious.
Then, I should make decisions as follows? ：

• #1：There'd be no problem in not bothering to tag ratio.　Because Even if strange(?) ratio Does or does Not match the already existing Tags ^{(for particular exact ratio)}, ratio metatag search is still valid, like ratio:1.78.　
• #2：I am pretty sure "16:9" and "9:16" are two different things. That's self-evident.　Is that correct? If so, I will follow it.

Out of curiosity, does the bot have a specific list of ratios that it searches for, or is it just whatever ratio tag is meta?

There's a list of what the bot tags on Pup's profile.

1. Yes.
2. Those are different things, of course. 16:9 is landscape, and 9:16 is portrait:

Hm, I was right, it was exactly what I had imagined.　But it's still good to hear things, I think.　Thank you
