It´s true that´s a problem that happens all to often. Mod creators should think of that when they create mods.
I do create mods myself and I always try to remember to check my file-structure before I release them. If there´s a special file-structure or installation procedure I include that in my mods readme file.
But you could simply forget to do that and that´s a real problem. I hope I don´t ever forget to do that because it just piss people of.. and that´s something I don´t whant
