Is working on a proxy project legal?

Question

proxy

There is a project found through upwork.
Its essence is a kind of anonymizer, but not for anonymity, but for visiting web sites through a proxy, i.e. for some security, because they also replace the video player codes with their own, for example, they filter some js scripts.
It looks like this: you go to the site, drive in the address of another site and see its result on the screen, but with a different video player and filtered js scripts.
The idea of ​​the project does NOT carry anything "hacker" or "illegal" there. But I’m already just in a kind of paranoia about what is happening and I’m really afraid of how our bodies can evaluate it in theory.
Is working as a web programmer for this project a legitimate activity?
In connection with these last laws, I no longer know what is possible and what is not. It seems that nothing is possible anymore.
The very idea of ​​the project is interesting to me and I would like to work on it, because I like working with servers, Linux, etc., but if our employees can evaluate this as an illegal activity, then I will not start.
So, is this legal or not?
Where to read the laws and what, concerning any programmer?

Answer 1

On the track they sell "left" anti-freeze. The cops come and imprison not the seller, not the owner, not the one who made the anti-freeze, but the carpenter who made the rack on which the anti-freeze stands.
Your fears, it seems to me, are from the same category - the carpenter did not know that they would trade leftist from his rack.

Answer 2

Any programmer is primarily concerned with the law of karma. I foresee that people of the epileptoid type are unlikely to like such reasoning, it is somehow off topic. :) But any developer really needs to think about his potential first of all, so if you rob an apartment, then the lack of a master key and the inability to use it is a much more primary obstacle than the police. :) It's the same in more legal cases, first of all think about money, time, experience, other components of your potential, or karma.

And so that my answer is not deleted (I love reliability), I will also answer on the topic:as long as your software doesn’t even exist, it can’t steal anyone’s information or cause losses, so it’s still impossible to prove its harmfulness (malware, spyware, fishing), that’s when it will, and when it’s announced where it should be, then there will be a real risk.

PS Several months of work on a project that violates copyright law.
And work on a project that violates the confidentiality of private data (spyware).
Or rather, even two spyware, there is also my pet project.

Most likely, here we are talking about copyright infringement of the authors of the primary content.
And not in the Russian Federation, but in the West , violations of this type are taken much more than seriously.
But, if you are not the founder (owner) of the project, but if you are just a technical performer, then bribes are smooth from you.
If we are talking about a violation in continental Europe, and not in the UK and the US - then your situation is a bit better. If in the US or UK - your risks are higher.
