PSA: some FL websites will use your phone number for spam advertising

Nowadays there are a lot of FL websites out there that advertise PRCs services.

Use a prepaid card if you want to book them.

This is because some of the web administrators will make use of your contact numbers to mass-advertise their services.

Here is how it works.
1. You call a girl to ask for booking (for new customers only).
2. The girl will check with a "manager" through Wechat whether you have any bad records (eg, fly aeroplane, rough attitude, run away without paying, etc).
3. The "manager" will inform the girl that you have good record or bad record.
4. If you have good record, the girl will accept your booking.

Your number will be stored on record by the "manager". I have noticed that there are at least 2 groups of "managers" out there. The "manager" is usually not the OKT but rather the website administrators themselves.

Unlike a previous thread mentioning that you can choose not to give out your phone number, you can't in this case as your number is automatically shown when you call the girl to make booking.

And there is usually no way for you to opt-out if your number is used for spam.

One of these website is 天上人间. There were some other websites before and I have managed to opt-out by posting in their website.
