In light of recent events regarding RealDebrid we do not recommend people use addons powered by RealDebrid for their Kodi library, and we strongly do not recommend that people pay for RealDebrid service.
You may still promote these addons in the community, there is no ban on promotion of usage of these addons. They are simply not recommended as they likely will not last or remain functional for very long.
What is forbidden is encouraging others to pay for RealDebrid without making this fact clear to people, as many people may not have heard the news and would waste their money on something that may not work for the next few months.
It should be noted that snarkiness or rude comments towards users who wish to not pay for RD due to this or any other concerns are considered uncivil behavior and violate rule 1 of the community rules.
Worst thing is that some addons had the Debrid service locked to use RealDebrid, so now those are effectively all broken. Many of their Devs and community members of the OG addons community insisted it would never happen and that people were being too paranoid.
