@name           GitLab - Hide bot messages (read the description!)
@namespace      github.com/openstyles/stylus
@version        1.0.0
@description    Some organizations that use GitLab have some bots configured, and those bots can be quite noisy in merge requests. This User-CSS can hide the message from such bots. This style needs to be tweaked to your own needs, manually adding the bot usernames.
