 This IP has been employed by a vandal. It is one of many IPs in the ranges detailed in the following query: . Established editors of several pages related to the development of nuclear energy in Argentina (especially Huemul Project, National Atomic Energy Commission and Ronald Richter) have identified a common pattern of highly biased and disruptive edits from IPs in these ranges, which point to a single editor. This editor has made several crude attempts to pass as different people, and accused others of of vandalism and of having a biased POV themselves. The editor in question has also personally attacked some of those who revert or correct his/her POV additions, and often resorts to misleading edit summaries to revert those corrections. Finally, this anonymous editor continues to edit from multiple IPs and refuses to register under a username, being well aware that such a behavior prevents administrators from blocking him/her.

For details, consult the contributions of this group of IPs in the aforementioned articles and talk pages. If you find this IP blocked, please check the facts above before unblocking it or taking issue with the measure and the responsible administrator.
