As to Erika.. I checked the definition on harassment on English Wikipedia. It fits perfectly. Erika is not demure, however I know her well, have worked with her on several projects and I have OBSERVED how she has been harassed, how she was made impossible as it was made known that projects would be boycotted when she is involved. When you look at the latest altercation that got me banned because I spoke up for her, it started with someone who was banned for edit warring in that week, starting with accusations of bad faith. It followed with someone new to Wikidata asking for her ban. That is not infighting, that is harassment pure and simple. I do not care who does it, when that starts to make a difference it gets even worse.
As to OmegaWiki, all labels for items in Wikidata have their own attributes. By design Wikidata does not know how to handle them. Dictionary attributes belong to each label. Given that there is plenty of other work that can be done, I do not interfere in this except for noting that the current design is broken.
