Anyway, here's a test, start paying!:
I had checked several of your addresses that you posted and they all had received at least .00001 BTC from laxo.
You are correct, I just imported the privkeys, and except for the first address (which may have been missed because of parsing errors when scraping) every single one of the 1600 addresses I posted was paid 0.00001 on 9/25 over a half-hour period, in the order that they appeared in the post, for a total of 0.01599 BTC.
Note that for a standard txfee of 0.0001, this is unspendable dust money; 1000 satoshis vs about 3000 satoshi min fee to send them based on the data size of a transaction. Spending all 1600 at once is also a non-standard transaction larger than MAX_STANDARD_TX_SIZE. You don't really want this dust, and because of the difficulty most will have spending them and the number of recipients included in one transaction, Laxo trade is spamming up the blockchain with what will be unprunable transactions.
How did you create/import that many addresses?
Since the inputs are essentially unspendable would you consider donating them to the miners, I believe I read about someone making some kind of script that allows you to essentially make a no output TX (the effect is that the miner that includes the TX in the block receives the entire amount in TX fees, although I am not sure how well this would work with that many different addresses/inputs). Another option would be to try to send a .0001 TX to yourself and include a .01598 TX fee, this may or may not get confirmed but I would only imagine that any pool with smart enough custom TX policy would include this TX in a found block.
EDIT: another option would be to wait however long it takes for the number of TXs to increase enough so that the standard TX fee would have decreased - this would likely accompany a much higher bitcoin price and likely a lower block subsidy - there is no clear cut time-frame for this to happen but you would simply need to wait long enough for the rules to change over time.
A third option would be to wait several months (or several years) so that the last time the inputs have been spend would be as long, giving them otherwise higher priority to have a TX that consolidates the inputs to get confirmed. You would likely need to wait long enough so that the rules that most pools follows changes (or get lucky and a pool like eligius that allows non-standard TXs to be confirmed will confirm your TX)
EDIT2: Looking at the TX that send the .00001 to 1PA16Zr4tAriJr6ZUKhBpMHNVuyaWxWBxC (a random of your addresses) it looks like they sent ~.42 BTC, which, IMO is a lot just for advertising that may or may not be effective. I personally think it would be more effective to spend this money on a signature campaign or advertising on the forum
