> What are wildcards? Some blocklists use wirdcards to block all subdomains for a domain. Wildcards look like this: \*.example.com The asterisk (\*) means that anything can replace it, and hence, in this example, any subdomain of the domain example.com will be blocked. Examples of domains that would be blocked: news.example.com something.else.example.com example.com Please note that the wildcard can only be placed as a prefix (before the domain), and only one wildcard is supported per entr…

> This article describes how to block/allow domains on Android. For iOS check [this](https://community.blokada.org/t/how-to-manually-block-or-allow-additional-domains/408/) article. The easiest way to do add domains to Ad blocking / Blocked Hosts or Allowed Host is to search the Host log (which is a submenu of Ad blocking) for the domain you want to add.

I’m using just one right now (OSID), although I’ve often used two or three at a time. The issues I’ve had with multiple lists is that sometimes certain websites or other internet resources won’t open and I can’t figure out why. After spinning my wheels for a while, I finally remember to stop Blokada, which solves that access problem. Then I switch host list to see if that will still block ads but fix my specific non-access issue. So that’s why I change host lists. Also, using multiple lists will complicate potential access problems.

I don’t see any way to extend the 30-day closing of a support issue other than reposting. Good luck! Maybe someone else will chime in? (Karol?)
