Currently the IRC feeds display partial blocks as if they were a sitewide block. Example:
On wiki: Arcversin (talk | contribs | global | block) blocked Example (talk | contribs | global) from editing the page User:Example with an expiration time of indefinite (autoblock disabled) (Test block: irc feed test)
In IRC: testwiki * [[Special:Log/block]] block * Arcversin * blocked [[User:Example]] with an expiration time of indefinite (autoblock disabled): Test block: irc feed test
