Description

I get a following message:

The page was blocked because of a matching filter in Peter Lowe – Ads, trackers, and more.

The issue persists regardless I click Proceed button.

Links under this domain, that failed for me, were leading to surveys from a newsletter I subscribe and I wanted to fill these surveys.

My quick search shows that the domain is used by MailerLite and I actually see no reason why it should be blocked under any default filter lists.

Browser name and version

Google Chrome
Version 142.0.7444.162 (Official Build) (arm64)

I clicked the "Proceed" button and the page rendered fine.

My quick search shows that the domain is used by MailerLite and I actually see no reason why it should be blocked under any default filter lists.

It's included in my list because MailerList use this domain for tracking clicks (and opens) from emails, as you've seen here.

Yes, and this is expected behaviour of this domain.
Why is it on the list then?
On the list, that is not an additional "block trackers" list, but on a default one?
By default I expect, from an ad blocker, to block ads, not other things, that I don't expect to be blocked.

But let's say that I may see it differently, but the domain should be there in the list - the Proceed button, which I understand should give me control of the behaviour, that I understand implications and want to be taken to the final site, did not work - it has fallen into an endless loop of bringing me back to the very same message, so that I could endlessly "proceed".
This is, by all means, unacceptable, as it does not work as intended, if I am given the ability to proceed, but it doesn't work.

And just now I have a problem with another domain, where Proceed button doesn't work - endless loop again.
This time it's a registration confirmation link to a job portal.
The domain is https://e.customeriomail.com and I cannot provide a screenshot as it contains a part of URL that is confidential.
I'm not sure, if taking this into account, we still should discuss a domain/filter list issue, or is it an issue with uBOL in general?

By default I expect, from an ad blocker, to block ads, not other things

uBO Lite is a content blocker, not an "ad blocker". The summary description in the webstore is:

An efficient content blocker. Blocks ads, trackers, miners, and more immediately upon installation.

endless loop of bringing me back to the very same message

So far I haven't been able to reproduce, when I click proceed, the browser navigates to the destination URL. For the issue here to be actionable, I need to be able to reproduce.

Fair point.

Is there any way I could help with that?
I don't know why it doesn't work on my end as expected, as in past I didn't have issues like that.
If there's anything I could check on my end, I'd be happy to help.

If you open a new tab to https://google-analytics.com/, uBO should block the navigation attempt. If you then click "Proceed", does it properly navigate to https://marketingplatform.google.com/about/analytics/?
