It's generally recommended that if you post in the wrong community rather than delete content and repost you should cross post to the relevant community to avoid this happening, assuming the community allows cross posts.

Thanks for the advice, on the first post I made I wrote that it was an error so that no one would give me likes and of course make rewards, because my goal was to post in the community for which the post was made, but mistakes happen in life.
I don't know for sure but that community may not accept cross posts.
Thanks again for your advice.

Mistakes happen. It's just a bit perturbing that HW are starting to take this approach with deleting the mispost and reposting. I personally don't like cross posts and I know quite a few others don't either, but it's generally the only solution. Another solution in this case could have been to message Galen on the weekend post and let him know your mistake with the link to the post. He's a pretty chill sort and I'm sure he would understand. He might even have a chuckle about it with you. 🙂
