Well even if you don't end up wanting an instagram, I always tell everyone starting up to claim every social media channel mainly as a defense against impersonation. This includes purchasing your domain name. If you are set on this name that's fine you could add an underscore (Happy_Linda) but if you can pick something else do that. Also there are tools to check availability such as http://knowem.com/. As far as picking a name this tool is cool http://kittyscammodels.com/generator/ (just don't sign up with them though they're a virtual studio for streamate)
I've been wondering about this as well. I use ProXPN to 'locate' myself in a specific place, such as back in the UK when I want to watch BBC. I assumed that camming through it (or any VPN) would really limit the quality of my stream. What kind of stream are you able to push through your VPNs?
FYI, I'm probably should go higher, but typically 800x600 24fps.
This is the ejaculating dildo I have, and I love it. It's easy to shoot with, even POV stuff, the fake cum is convincing (but you can get another brand of it if you like). The only immediate drawbacks are it's not so easy to clean because it's so textured so goop gets stuck to it easily, and also it's very thick so you'll need to warm yourself up before you use it.
I'm going to caution you about using a Bad Dragon dildo. I bought one more for myself than for work, so it didn't have anything fancy (no cumtube, no suction cup) and so the appeal is primarily in its girth when I stream, which means the only thing guys have been willing and wanting to pay for me to do with it is stick it up my ass- which, with a small toy, takes (for me) still about half an hour prep time. Of all my videos that are me using dildos, the ones featuring my BD dildo sell the least, and for the large price that they cost (and they really are awesome), it might not be a wise investment. However I will say, I've seen lots of BD stuff with the cumtube feature, and so it seems those two things might be linked, fetish-wise, and your results with a cumtube in a bd video/stream might be very different.
