The reason why I believe they're all the same user is because his actions on meta and es.wiki are all to try to descredit the actual Wikimedia Ecuador user group proposal. The user Citizen www has created his account and shown an actual knowledge of wiki-editing, when he created Wikimedistas de Ecuador page. Off-wiki, the people signing on that meta page had told me Citizen www is an actual editor of past years, calling him "one of the best editors on Wikipedia" but were unable to tell me his real username. He declares himself "Coordinador Ad Hoc" on his meta page and here, which is almost the same behavior Nihilo had in the past when asking for unblocking on es.wiki here. The ip's are the ones from where he had edited before on that request and here. This is needed also if this should be taken to an outside-instance, because the problem's going off wiki too. --Edjoerv (talk) 21:03, 7 September 2015 (UTC)
CU comment: Some technical notes:
Nihilo is not registered at Meta-Wiki, thus can't be checked.
Even if we did a cross-check with eswiki, Nihilo's account at eswiki and eswikinews can't be checked either because his most recent edits are from 2009 and CU data don't last such a long time.
The IPs you mention from the unblock request faces the same problems:
Multiple accounts are not forbidden unless they're being abused. And talking about the two that are registered in Meta, just only one have editted and I can't see any vandalism or other kind of abuse which may justify using this tool. Unless you can convince us otherwise, I'm leaning towards declining this request for all the problems said above. Maybe ChapCom would be willing to have a look at the issue though. Best regards. —MarcoAurelio 11:06, 8 September 2015 (UTC)
