Javier Arenillas
I am an IT specialist, SEO analyst and court-appointed IT forensic expert, with a master's degree in cybersecurity. I run 3CWeb Marketing Online, a digital marketing agency, and through Olvidum I deal with what is published online and harms a person or a business.
Who I am
I have spent many years working online as head of 3CWeb. My core trade is SEO: understanding why Google shows one result and not another. For a long time I used it to get clients higher up. Now I also use it the other way round, so that a news story, a profile or a review stops showing.
As a court-appointed IT forensic expert (perito judicial informático) I certify what is published online so that it stands as evidence, and I defend that report in a Spanish court. The cybersecurity side covers the rest: how accounts get stolen, how impersonation is set up and what has to be preserved before it disappears.
I work with a law firm. They handle court claims, civil or criminal; I prepare the evidence and the requests to search engines, platforms and newspapers.

How I work
The first thing I look at is what Google shows, what the platform allows and which rule applies. With that I can tell you what is achievable and by which route. That review is free.
If I see no real prospects, I say so and do not take the case.
Every request rests on something specific: the GDPR, Spanish data protection law, the right to honour or the platform's own terms. No tricks that work for a week and then backfire.
Tell me what is happening
I review your case for free, in English, and tell you plainly what can be done.
