Thanks for testing! In the future, please do responsible disclosures, for example by DMing @k00b or me in TG. You can find us in this group: https://t.me/stackernews

I tipped your post with 15k sats but that also wasn't a good idea. It now shows up in daily top posts, lol

While I was writing my Github issue for this bug, I looked for SN's disclosure policy and couldn't find it. Also, I don't have a phone, so Telegram wouldn't have been an option.

Ah, yes, you are right, sorry.

I forgot that there are no instructions regarding this in the README. I will add some.

Thanks again!

In all honesty, the only place I checked was the FAQ. I didn't even think of checking the README in the Github repo -- but next time I will.

What do you mean? I see you are a new user. Did you mean you didn't know your post can get tipped?

it was just a problem of connexion , i clicked twice on the comment button so the comment got duplicated :)

Ah, I see, haha

We should maybe also add some deduplication in the backend. So you don't get billed twice just because of bad internet, hehe
