Can’t think what the “ha” would stand for in their analysis, but the se and xx can be indicators of adultness when you have a naive algo for dealing with bot spam domains for adult-content-as-spam:
Some even started using multiple X's (i.e. XX, XXX, etc.) to give the impression that their film contained more graphic sexual content than the simple X rating. In some cases, the X ratings were applied by reviewers or film scholars, e.g. William Rotsler, who wrote "The XXX-rating is for Hardcore, the XX-rating is for Softcore, and an X-rating is for comparatively cool films." — https://en.wikipedia.org/wiki/X_rating
That said if they think the domain is a soft hit they should look at content, site age and classification in e.g. bluecoat, etc., which would counter the soft domain indicator. If the site allows comments and doesn’t always successfully moderate or filter out adult bot spam links, that can make even clean content sites get filtered. To be clear, not! aware of any spam at this site, but as a heads up to anyone w/ open commenting, comment engines that allow a website link are often bot-bait.
