Block Ads & Trackers

Prevent Infections

If you can’t access evil domains, you can’t get infected. Simple.

Custom Access Rules

Block lists are not 1 size fits all. Customize them to your liking.

50% of an average website is ads and trackers. Blocking them makes pages load faster.

How it works

Magic and unicorns are at the heart of R.O.B.E.R.T.

House Block Lists

Select which block lists you wish to apply on all devices by toggling a single switch.

Custom Access Rules

Create custom block lists of domains or IPs of your choice. Whitelist domains you wish to access.


Reduce Tracking

Trackers can link your activity between devices, even if you use a VPN. Blocking them on all devices is the best way to significantly reduce the tracking.

See Fewer Ads

No one likes ads, especially the ones that deceive you, follow you and know who you are. Block them at their root.

Use Less Data

Most sites have more ads/trackers than actual content. By blocking them you can use your precious data to view things you actually want, not spam.

Instant Changes

All R.O.B.E.R.T. setting changes are instant. There is no need to wait or reconnect. Nobody else offers this feature.

Totally Customizable

Create a unique set of blocking/whitelisting/spoofing rules to control your network your way. No one-size-fits-all model.

Reduce Risk of Infection

We block botnet C&C servers, malware distributing and phishing sites so you have a much smaller chance of catching an Internet STD.

Block List Overview

We offer the following “house” block lists. Each one encompasses several community maintained lists, as well as our hand curated whitelists to remove false positives.


Contain the worst of the worst. Sites that are known to distribute malware, launch phishing attacks or botnet command-and-control servers used to communicate with already infected machines. There is no reason to ever disable this list unless you’re doing malware research.

Ad + Trackers

One of the most comprehensive ad and tracker blocking lists out there. 4x the size of Easylist, hand curated to remove false positives that plague most community maintained lists.

Social Networks

Social networks are one of the most pervasive privacy violators out there. Much like with crack cocaine, it’s hard to go cold turkey. We’ll make it easier for you. This list will block all social networks and their associated trackers. If you must use 1 of them, you can whitelist it via a custom access rule.


Internet is 90% porn, so this list is the biggest one we have. Blocks all sexually explicit content. Handy on kid-friendly networks and those morally opposed to pornography.


Blocks all gambling sites. Prevent yourself or your employees from gambling away their cars and homes.

Fake News + Clickbait

Sites that intentionally, but not necessarily exclusively, publish hoaxes and disinformation for purposes other than satire. Source 1, Source 2, Source 3.

Competitors (Other VPNs)

You’re using the best privacy tool out there – Windscribe. Most other VPN companies track you across the web with their ads and compromise your privacy before you even become their customer. Block them all!


Cryptomining services that mine cryptocurrency in your browser. These can slow down your computer if used covertly.
