Same onion address, different people

#1

I have traded 4 times now with the same peer (same onion address) but every single trade the name and account details from the peer were different. It is like several different users are sharing the same onion address. Is this an issue?

Not necessarily.
Let’s say you’re in Brazil and I’m in the UK, but I have family in Brazil. One way of doing remittances cheaply is to send you bitcoin and have send BRL to one of my family members in Brazil. We could do multiple trades and I would never give you my personal details. Instead I’d be giving you the details of different family members in Brazil.
Or this may be someone with multiple bank accounts. Although 4 different ones seems excessive.

It is 4 different persons (names) and they are always buyers (takers) of btc.

Assuming this is a bank transfer, maybe they’re aware that your bank doesn’t really care about the name of the account owner, only the account ID. So they’ve been sending from the same bank account but different aliases? Or maybe they’re just providing services to different people and will have different people send you the fiat.

What are the identifiers you are seeing? Full name + bank account ID?

Different account numbers and different names. My guess is that the final user (payer) is not using Bisq, and the one that uses is Bisq is some kind of service provider

Yeah, that’s one of the applications that Bisq could allow. However, the final users of that trade would have to trust the Bisq trader buying bitcoin for them, to then send them the bitcoin after.
I think what I’m suggesting in this thread could help rectify that.

Yeah. it could be that someone is providing a service. We had some users here claiming they do that already.

However it could also be someone stealing bank accounts or scamming people to send payments to different accounts while he enjoys the privacy of bitcoins.

There is really no way of knowing. It could be an issue, but it also might not.

The account is not even one month old. That does not support very much my guess of being a service provider

What payment methods is that peer using, if you don’t mind me asking?

I don’t know either if this is an issue or not. (If people invent new usages, that may be interesting).
But, I would however recommend to be cautious and to investigate a bit.
And preferably avoid doing many of such transactions if things are not well understood and if you have doubts.
If the offers are too good (is it the case ?), this may be a warning bell.

When the DAO will be released, the contributors will have to vote on the reimbursement demands.
A user who has been scammed N times by a same onion may perhaps have some difficulties to be reimbursed for the whole batch.

The payment method is SEPA

He´s been always a taker buying 3%-4% above market price. The problem is that if he is a taker I cannot avoid him taking my offer, unless I completely block him.

@Homard what possible the attack would be possible here?

It is a bit suspicious that he is always a taker and that it is always the same payment method.

This peer may very well be scamming other people to send funds to accounts that he gets from Bisq so he can get the BTC in return without risking his/her anonymity. The risk for OP is that police reports could be filed against the OP and funds could be requested to be chargebacked due to theft.

PS: You might want to consider at least temporarily putting that peer on the ignore list. After a while if you don’t have any issues with your bank over these transactions and if the peer doesn’t get network wide ban, you can remove him from the ignore list.

This might be a friend of mine. Because he is very knowledgable with BTC and he has friends that are not very knowledgable but either want to get their first BTC and learn about it or are interested in purchasing products and goods that are only availabe for BTC purchase like Openbazaar for example.

And he is willing to help his friends in that way as to at least get their BTC safely. Unfortunately governing bodies and regulations make it difficult for specific markets (in specific countries) to establish themselves publicly. Good thing we have markets like Openbazaar.

You can block peers by onion address in the settings.

I and @keo have looked up for disputes with that onion address and nothing suspicious was found and the users was also one time a BTC seller and used another payment methods as well. So at least that he was not always the BTC buyer decreases the risk that he is a “stolen bank account scammer”.
The possibility that he does trades for friends is not unlikely.

Finally this peer is a fraudster. My bank has freezed 2 of his payments because the sender has reported that his account was stolen. Do not take any offers from him!!

Ok, arbitrators need to be aware of this activity and it is good to keep a list of all the bank accounts this person used.
