There’s been a huge effort to discredit the victims of this horrific type of crime. Sure, there are people out there who are paranoid, but gang stalking – also called organized stalking, community stalking, group stalking – exists. It’s a combination with harassment and there is not always a clear category for much of this in existing legislation. In addition, investigating this phenomenon is very expensive and time-consuming, requiring specialized expertise (notably in the field of IT).

Crap about the misogyny on Wikipedia
The following Wikipedia page, however, should never have been approved and I‘ve just added some information in an effort to help put a stop to the relentless mocking and ridiculing of genuine victims of stalking and harassment: https://en.wikipedia.org/wiki/Gang_stalking
However, not surprisingly, my edits were reversed. I expected that. This almost never happens with my Wikipedia edits, but it did also happen within the context of my own stalking, namely when I added information (a documentary and a series of articles from the local newspaper) about the notoriously violent culture of Portsmouth, in Hampshire UK. (It is known for that throughout the UK, as well as for its excessive insularity.) They previously happily let me add information to the Wikipedia page about Boris Johnson’s wife, by contrast, about ties to Russia and a few other bits and pieces. You’d expect a storm of protest. Nope, not a single letter was changed. I have edited other politicians’ pages. Not a problem. I have edited various scientists’ pages. Not a problem either.
This is about misogyny, because in effect, the existing Wikipedia page said and now still suggests that women are crazy. No, they are not.
This is what I had written on Wikipedia:
However, it is important to emphasize at the same time that organized group stalking does exist. An example is the [[EBay stalking scandal|stalking of Ina and David Steiner organized by eBay employees]]. See also the following Wikipedia pages: [[Stalking_by_groups|”Stalking by Groups”]] and [[“Mobbing”]].
I had also referred to a study by Sheridan, Davies and Boon (2001), which had been accepted on a different Wikipedia page. This too has been removed. (I find it sickening that in this manner, Wikipedia contributes to the vilification of stalking victims, most of them women.)
HOURS LATER, I received this message on Wikipedia.

End of crap about the misogyny on Wikipedia
Illustrative for your understanding of the phenomenon of gang stalking or whatever you want to call it may be the way the maffia supposedly operates within the context of people who don’t keep their mouth shut about crimes. Scientology does something similar, so I understand.
Examples of gang-stalking or group-stalking
- Pizzagate, in New York, US
- Vapegate, in Portsmouth, Hampshire, UK
- The stalking of the Steiners (Ina Steiner MBA and David Steiner) organized by eBay staff in the US
