I play at the site - and I've used the chat.
#1 - it should be moderated. I witnessed the spamming the other day. Wildly racist comments...personal details..threats towards the person in question.
#2 - No deposit = no chat. Wouldn't prevent spamming, but at least your site would get a little BTC out of someone determined to chat.
#3 - Most forums (including this one) have a set time that a person must wait between posting. For new players, even a 15-30 second wait between posts, and an auto-flag if someone posts the exact same text 2+ messages in a row should be greeted with an extension of the time-to-wait between posts (or the ability to chat being turned off)
I like the site. I've lost more than I've won. I've researched variance after getting frustrated (I had zero winning hands in a 19 game stretch), and while things like losing 15-20 hands (I play blackjack) in a row are indeed rare, it's not unheard of. When you play 10's of thousands of hands - you'll see it happen. Here's the link that shows why losing streaks occur more than winning (vs the dealer)

I dislike a few of the blackjack rules - but a site that lets you play instantly without 1 confirm, and let's you withdraw as soon as there's 1 confirm is great. The games play fast, and with the exception of the recent down time, it's a pretty zero hassle site to try and make a few BTC on and not have to wait hours or even days (which occurs at other sites) to get the BTC back into my wallet.
