From what I've seen, not everyone has been hit with steam's link filter for links from steam chat (may be a beta client only thing at the moment), although it's safe to assume this will be rolling out completely at some point. I know it's to cut don't on fishing and user's who suffer from PEBKAC, but I don't fall under that category, so there's no need for steam to be inconveniencing me. With that said, I made a userscript that simply redirects the page to whatever link was filtered.
Kinda sad Steam doesn't offer an option under the settings to disable this. This shouldn't be an issue in the first place.
