I don't think anything you do will help. If they want to send bitcoin to everybody, even in small amounts, then so be it.

You will be wasting your time to try and 'blacklist' them and its not worth the effort. Also, to try and give them a bad rep here will just give them more exposure so in a way they will succeed as they are getting their name out there. Its of little use to try and tell people not to go to their sites and or not to get involved with these sites as some will still do no matter how many warnings you post.

Personally, I don't care, if the payments confirm it means I have a little more dust, if not then so be it.

Yes, I recd. that much from Laxo trade, but I won't sign up on there site for that cheap. I also recd. 0.0001 from an asshole advertising "child porn", here is his address http://blockchain.info/address/1CPxxxZkKeBYDgvX7pmiUZnMRxqELFV7Yb

i received 0.00000001BTC from this:

1BSmartoUnHz32AAdPKcc7cGGC3DiA4RSh
1MAdS7aPszWG4EYgBpbF9mnGUi5ChbMu8d
1NU3fZCJm5TTkEj5HcSvmUhyXREyoeoohL
and
1LaxoTrQy51LnB289VmoSAgN6J6UrJbfL9  (more than 0,00000001BTC) and i dont know why


what i will do?: nothing... if they want to send me free BTC they are welcome...

they are pretty annoying especially when the tx never confirms and it get stuck on wallet forever saying unspendable amount in wallet

They are getting addresses from recent transactions on the blockchain, any node has that data.

I have not receive any 1 satoshi transaction.
Just ignore them and problem is solved.

Except that's the problem, you can't really ignore them when you get notifications about them, and not to mention some of them confirm and which will then make you have to pay a bigger transaction fee, so it is a problem.

I think they are actually getting the addresses from posts on this forum. There is another thread where someone posts 1,600 BTC addresses and all but one of them received a TX from laxo trade within 30 minutes.
