If you're seeing paywalled articles where there was no workaround, please let us know (hn@ycombinator.com is best). But if you're seeing paywalled articles with workarounds, that's normal. Please don't post about it, since it's off-topic and has been discussed many times. We all know the paywalls suck. It's just that HN would suck worse without NYT, WSJ, Economist, etc., articles.
