On English Wikipedia and Meta, the following text is triggering the spam blacklist:
<div style="overflow:auto; height: 10em;"/>
The error message is "The following text is what triggered our spam filter:
overflow:auto; height:". I was able to work around it by reversing the
"overflow" and "height" properties.
I tried to track it down in the code, but I couldn't find the culprit. It may be
related to the setting of $wgUrlProtocols on the Wikimedia servers, but I don't
know that that setting is. The setting in DefaultSettings.php wouldn't have this
problem. I don't have access to a local MediaWiki install at the moment to test.
I expect we're filtering out 'style="overflow: auto"' since it's often used in
mass spam and vandalism attacks; this would be set in $wgSpamRegex.
Correct, that is indeed in the filter.
i expect spammers will soon start to revert those attributes too, or inject
random cruft to obfuscate them. the spam-regex would need to be more flexible to
catch that. and would then prevent any such workarounds from working any longer.
This is disappointing.
