I think we should blank the task descriptions of Phabricator spam. We shouldn't be indefinitely hosting/outputting spam. Alternate solution would be some kind of deletion of the task, but I'm not sure that's possible.
I don't really like that the Trash tag/project is used for both actual spam and spam-related tasks.
One idea would be to split this tag/project and then associate different behavior with spam tasks (tasks marked with a "this is really spam" tag/project). For example, we could automatically mark such tasks as "noindex" and perhaps have a bot or script blank their descriptions.

Project description is clear. So whoever uses it for spam-related tasks shall stop that. :)
