Wikipedia policies on original research and reliable sourcing
Hi Alejandro Del Pielago,

Thanks for your contributions to Wikipedia. Unfortunately, some of your edits to Collatz conjecture have been reverted. Wikipedia has strict policies about what constitutes valid sourcing (see WP:RS) and forbidding the addition of original research (see WP:OR), and it looks like your additions were not in keeping with those policies. If you'd like to discuss this, you can use the article's talk page.

All the best, JBL (talk) 23:04, 26 December 2019 (UTC)
