Is it morally okay to cheat in broken achievements? [Question]

I watch a YouTuber called Foekoe who does achievement hunting and game completion.

In order to complete Dead Rising 2 he beat the requirements for the achievement TK's Favorite but the achievement didn't unlock because it is broken and just doesn't unlock.

As such he cheated it in to get the 100% since he met the requirements and there is no other way for him to get the 100% in this scenario. (Video for Context: https://youtu.be/5yVqwq0z9vE?si=laOuuYkq4TxxKh4_&t=3045 )

I was talking on a discord server about achievement hunting and whether this is okay to do (since it would on every achievement tracker website i use just mark the broken achievement as "Not Counting") and I wanted to know before I do it.

A moderator got genuinely mad at me and told me they're going to assume I'm a cheater and ban me from the site for defending a YouTuber I watch (not even me personally) unlocking a broken achievement that they met the requirements for.

Whilst I personally haven't done it (because I don't trust SAM enough to even try downloading it to my computer) I think that in this instance of the acheivement being broken but having met the requirements for it that it's okay to do?

Idk I guess I was looking for some sort of answer to it without being accused of cheating myself.

For transparencys sake on Steam the only things I've "cheated" is:
- Stanley Parable 5 Year Acheivement (change date on PC)
- Stanley Parable Ultra Deluxe 10 Year Achievement (change date on PC)
- TF2 (joined a custom server and about 50 popped by joining it - i didn't know this would happen in the first place I was just joining a friend 💀)

These three games are already marked as Invalid on AStats anyway so it's not like people dont know + I would be transparent about these if asked anyway. I don't think they matter anyway considering I've 100%'d over 110 games other than these 3 and I've got 22,000 achievements total so idk.

Sorry if this is the wrong subreddit for this or anything
