Alright, first of all, thanks and kudos to @GoEThe and @He7d3r for helping the community and me to sort this out.

It's been almost two weeks since the last edits on the Esplanada sub-page, and three weeks since the event.

Three weeks ago, I immediately:

• Posted an apology with explanation what went wrong and how I would prevent from happening that in future,
• Added the correct announcement,
• Spent a few hours that day chatting on Telegram with a part of Wikipedia in Portuguese community,
• Answered the questions on wiki.

I still have the page on my watchlist and do check for updates. If any requests or questions show up, I'll react accordingly.

I'm closing this task because I believe we don't need to keep this open for any longer.

You can always contact me by pinging on wiki or writing at sgrabarczuk[at]wikimedia[dot]org.
