I do not know if freebitco has such feature that allow their users to send funds to another user fast and free using the ID
If there was a feature like this, perhaps many multi-account users would use this feature to collect all funds into one place and then withdraw them, because the withdrawal fees might be quite large for free users and those who are still looking for free bitcoins from this site by using the free roll feature because of the income only a little under 5 satoshi or even less depending on user activity, I myself only get 6 satoshi per free roll every hour, so it might take weeks to be able to make this withdrawal where the minimum withdrawal is 30k satoshi.
But I'm sure if there is a feature where every user can send each other of course it will be misused even though I know that security on this site is also very tight with multi-account user accounts, but whatever it is, people will definitely look for loopholes to be able to get free bitcoins quickly and then collect them. all funds from the clone account to one account which becomes the main account to withdraw all the free bitcoins obtained from this site, but actually this site only lacks features for interacting with the admin or service support because whatever it is, it is definitely important for users to be able to complain about all the problems.
Fairly good point about this "fund collecting", also I would think that most people would use it out of reason that you get daily interest at freebitco.in , which is quite amazing feature I have to admit.
Combine that with referral net of alt accounts transfering funds between them and most likely they would abuse it to get their daily satoshi interest higher and higher.
One thing in your post makes my wonder why would you say they have "very tight" when it comes to multi-account user? Have you seen some examples of alt accounts banned or something?
I've never seen it but I've cursorily read several posts on this forum and also in several posts on other sites, but again what I'm saying is that even using features such as transferring funds from one user to another will definitely not be possible on this site, because they certainly also don't approve of abuse, so we are talking about the problem of abuse, seeing whether users are blocked or not, only they know because I have never tried it, but have seen other people's posts about it that they can't register other accounts on IP the same thing and such.
But apart from that, this site is definitely very strict and doesn't always pay too much attention to how this site works in preventing abuse so that those who play on this site are genuine users because for me the most important thing is that this site still pays its users, that's more than enough, but in the end At the end we were shown how their support works, now the response is a bit slow so it still seems to be piling up and there are still people who are still complaining about their problems in this thread which have not been resolved. but currently many are waiting for Thequin to return again on this thread.
