Yep, I really am averse to major avatar change in the first place. I understand if you want to enslave someone because their text gets you going, and yes this is a visual environment, but if you want the change AFTER the enslavement fact with no OOC discussion saying "hey if I enslave you, I want you to change... umm... everything about your avatar." Ummm get bent? Other than that, he's coughing up the money.
I can build a perfectly acceptable/hawt avatar for 100% free. Just built one the other day. Just to see if I could build an acceptable looking avatar, AO and all, hair to shoes, for 100% free. it CAN be done. Its not easy. But its possible. Now, demanding a certain skintone, skin style, makeup, etc... umm no. That costs money. Even if its 100L. Some people dont have that and dont feel like camping or splodering or whatever to get lindens and definitely dont have the spare cash laying around to buy lindens and arent artistically talented enough to build something for sale... whatever. Some people dont have the lindens. And they can be stellar Rpers. And while their avatar style may not be your choice, that's your option then to negotiate OOC with them, or reject their offer to RP.
By now I've amassed pretty much every forseeable hairstyle for thyri I could ever want (or not want, some of the hairs in my inventory I'll look at and say I dont care if it was free, why oh why do you have this?!). But when it comes to hair color.... black is a VERY hard color to bleach out. And even if you could quadruple process it to white, then you'd have to tint it yellow for the blondie look. 5 processes on any hair would be a nightmare and it would look like straw.
So some things just cannot be realistically done. Giant boob jobs, butt implants, stretching someone taller, squooshing them shorter, extreme weight gain or loss.... sometimes realism isnt as easy as moving a slider.
