Option to obfuscate information in the annotation interface
In some cases, it might be useful to hide or obfuscate certain information in the annotation interface on a task basis. For example, when annotating tweets, users setting up a task should have the option to provide rules that i.e. hide the username or replace username mentions in a tweet to not get "influenced" by external knowledge a classifier wouldn't have.
This feature would have to be implemented in such a way, that it does not interfere with the "clean data" stored in the database. Either by having an additional table containing alternative texts for a task or implemented directly in the interface (e.g. by injecting pre-processing code called on the view element)
