Ricci, since you were interested, here is the beginning of my new "career" XD
We (husband came with me) had an appointment to the livechat office 3pm. The girl made us seat, gave us tea, and handed me an information sheet to fill in (name, contact info). Then she explained me the different points of the contract, the payment system and stuff. I asked if it was possible to block IPs from certain countries, but it's not (or she doesn't know about it). Well, i don't think anyone in my family would use that kind of sites, so i don't really care. Tto tell the truth, i don't care AT ALL, but i didn't want to stay silent when she asked me if i had questions (looking interested, a job interview basic rule, even though they probably don't give a shit for that kind of job XD)
Regarding tax, it's quite easy: paid in cash after every shift, so not declared XD
(even if it was declared, it couldn't be under the "independant" status: unlike Europe/USA where girls mostly work from home, in Japan you have to go to the office to work, they have private rooms in the building - although you can choose to do it at home too, but you're still paid at the office)
Anyway, i told the girl i'd start on Saturday 10th (periods are coming tomorrow, so i have to wait), from 6pm to 11pm. It won't be a "full work" day, since we'll first have to set up my profile, and she'll show me how to use the comp and stuff, which will take like 2 hours. Then i can work~
She was vey nice, we talked a bit about other stuff, and she also told me that one of the models really likes France, and was actually working there to finance a trip XD
