Disclaimer: I'm owner of the geany.sexy domain.
A few years ago, I registered this domain as in my personal opinion this is funny, exactly what you consider as offending: the use of the word "sexy" in a completely different context, here for software. In my cultural area, "sexy" is actually used to describe nice and positive things, additionally to its original meaning. Hence I didn't see nor ever intend any offense or the like.
I do see use of this word might offense others and isn't used elsewhere in the same way as I'm used to. So I removed all occurrences of the word "sexy" on the website content on geany.sexy. Since the Geany project does not promote or even mention this domain anywhere, I don't see further action here.
I hope this helps the situation and we can focus on developing great software again. For further requests or questions, please contact me, as the owner of the domain, and do not bother the Geany project. Thanks.
