No, CoinDeal is regular and reliable exchange. If you do some research you will find positive opinions from users. This guy above me posted a site, where are 4 short shity reviews. It is quite fresh exchange, they are on the market for like half a year but imo they manage pretty well, recently they've entered the USA. There are a lot of trading pairs, good security standards, never had any problems with transactions or something.
I'm not saying that there are no good reviews, I'm just saying, that unless he's dealing with certain fiat currencies, there are better alternatives out there.
Also, the way you're advertising the exchange with is not going to bring you much credibility because it definitely looks like you're more of an official representative than a user of the platform.
Basing on CMC rankings this one is on rank 90 and i cant see a reason why i would use up this exchange if there are top ranking ones?
As said even on FIAT pairs there are exchange which is more worthy to be used on than on this one.
