@balloonsBe aware that eu.org is on our list of unsupported providers. Their domains will only work if used as your main domain, they are not supported as an alias or an addon domain because their name server setup requirements do not comply with industry standards.
Other unsupported TLDs I'm aware of include (but are probably not limited to) .pp.ua and .br, both for the same reason as eu.org.
As for freenom, they're rather well known for extortion attempts. Krydos and I have both lost numerous domains from Freenom. Once the domain becomes popular, they cancel the domain and replace the content with ads (which in my experience often served malware...) to extort you into paying for it to get it back. If you wait them out and re-register the domain after that, they have been known to just flag your account as abuse instead. Best thing I ever did with my sites was ditch the free domain providers.
