Never heard of this, so I had a look:
Exchange Summary
Total Markets: 1535
Total Trades(24 hours): 3938
Haven't heard of 90% of the coins listed either. Not that I look much at that stuff, but still.
Trading XMR would likely blow the top right off the exchange. One bot would increase their volume by an order of magnitude
I commend the initiative and effort, but can't recommend an exchange that
-puts new listings up for a vote, then utterly fails to act on the results (cough, Craptsy, cough)
-says XMR is a priority in Oct 2015 and still needs to be gently nudged 6 months later (Craptsy did that)
-supports 1500 shitcoins but can't bother with an innovative/fairly launched/top 10 coin (more shades of Craptsy)
-needs hand-holding tech support from (potential?) customers to sort their backend (I expect an exchange to know more than I do)
-only provides updates (in the form of lame/implausible excuses) on the previously promised pair when prompted by inquiry
Actually we have strict rules for fair launch coins, No ICO, no excessive premines, os even coins like DASH and ETH cant be listed on our platform.
I understand you are upset that is taken us longer to implement XMR that you would have liked, but Cryptopia is a small team with one dev.
We NEVER asked for hand holding, just hours in the day as i have a full time job and a family, we dont have endless budgets like Polo, Bitrex and Crypsty
We will happily refund all votes as you seem super upset that this has taken longer than YOU expected
The votes were paid? I forgot about that. It's reasonable to refund them when you can't/don't deliver. Craptsy did that to XMR also. That's the reoccurring pattern making me "super upset."
It was your responsibility to communicate difficulties and ask for hand holding when (in accordance with the paid "votes") adding XMR started taking an unreasonable amount of time/effort, not to wait until some enterprising member of the community reached out to you.
The newest version takes much less system resources to run. I wish your growing exchange great success with XMR and sincerely appreciate your refusal to list insta-mined crapcoins like DASH.
I would seriously consider leaving Polo for an exchange that doesn't facilitate IPO scams like MAID and NXT.

Unfortunately I read the Monero thread and can see a legendary member comparing us to Cryptsty for taking too long.
Kinda sad, I thought the XMR community was better than that,
We are happy to refund all votes since we cant work fast enough for you guys :(

Well, don't get sad about that.
Honestly i believe you had 6 months to deploy the coin and obviously you are using the oldish binaries, so that maybe a point from legendary members.
If you don't want to deploy Monero, just send back the coins, i am fine with that, it would be your loss guys.

We are adding it, its 90% integrated, like I said we just had a few issues.
We were just offering the refund due to the time it has taken, but we are a small site with so sometimes new features take a bit longer than the other sites with big budgets.
Just seemed a bit hash to be compared against a scam site like Crypsty thats all.
Anyway, should only be a couple more days until monero is live providing the new source works fine :)
Thanks

Now as you have the new binaries, it should be a rather fast deployment of MOnerO :D
No Problem, we all just were wondering why the heck it takes you guys so long to deploy it.
Well, don't take that personally, we just want MOnerO on your Exchange and we believe that it will take more ressources than you can handle (just in case, setup some more ressources).
Do you make an announcment to the users that voted for the coin, before the coin get's finally listed?
Kind regards,
elrippos.
I tend to like those guys at cryptopia
Get it on and XMR at your Exchange,
NOW!!!
