So, I tried to go to the last page of the Kamenashi Kazuya discussion thread: http://mydramalist.com/discussions/japanese-actors...
and when I tried to go to that last page, it came up with a screen saying that the following site was dangerous, and wouldn't let me access it. And, when I use the same tab to go to other parts of MDL afterwards, even though it lets me access it, it has a thing at the top that says that the website is still dangerous....
Help please?
Are you using chrome and do you have the exact wording? 
I'm a chrome user & the same thing happened to me, but I'm able to view the last page of the thread without any warning if I use firefox.
MDL isn't showing the first post on a new page until there are 2 or more posts for that page.  I tested this on chrome and safari for this thread. My post is the first for page 4, but it doesn't show up unless I make a second post.  I did that, but then deleted it so someone who can fix it can test it out as well.

If you change the url from "last' to the number of the last page, it works without receiving an error.

When trying the Kama thread link for page 18:
http://mydramalist.com/discussions/japanese-actors-actresses/769-discussion-kamenashi-kazuya-a.k.a.-kame?page=18#comments

There is a read warning page that pops up stating:
(In the browser bar)
Dangerous
Attackers on this site may trick you into doing something dangerous like installing software or revealing your personal information (for example, passwords, phone numbers, or credit cards).

(On the browser page)
Deceptive site ahead
Attackers on asianidolnow.net may trick you into doing something dangerous like installing software or revealing your personal information (for example, passwords, phone numbers, or credit cards).

The last page that works in that thread is page 17:
http://mydramalist.com/discussions/japanese-actors-actresses/769-discussion-kamenashi-kazuya-a.k.a.-kame?page=17#comments

My assumption is that the first post on page 18 is corrupted/spammed.

To get rid of the "Dangerous" in your browser address bar, simply restart your browser.
It could be that the issue is with images on those two pages. In particular asianidolnow is the source of one of the images. Chrome has a more aggressive  malware protection build in than that of Firefox, so it could be a real thread or a false positive.
Thank you all so much!!!

@Ji-N  This is what it said: Deceptive site ahead Attackers on asianidolnow.net may trick you into doing something dangerous like installing software or revealing your personal information.   And, yes, I'm using Chrome.

@theairtwit  Thanks! I'll try that to see if it works.

@Six  Thank you, as well! I'll try to do that.

@Juls  Thank you! That's probably the problem. Thanks for the help!
Interesting. Must be from the advertisement? But if you have a screenshot that would be great.
Sorry, for some reason it won't let me put the screen shot on here.....

But the exact wording is:

Deceptive Site Ahead
Attackers on asianidolnow.net may trick you into doing something dangerous like installing software or revealing your personal information (for example, passwords, phone numbers, or credit cards).
