A box just comes out of nowhere which says "chat with an expert". It happened once on Stack Overflow and once on Meta. Is this an ad? Isn't Meta supposed to have no ads?

chat with an expert

Here's the HTML for that weird box:

<div id="adviza-box" style="width: 380px; ">
    <div id="adviza-status">
        <img width="34" height="34" src="https://i.stack.imgur.com/owly4.png">
        <span class="hoverable">chat with an expert</span>
    <div id="no-adviza">
        <span class="hoverable" style="display: inline; ">not now</span><br>
        <span class="hoverable" style="display: inline; ">never</span>

Looks like this line does it:

StackExchange.ready(function () { StackExchange.adviza.init(170118, 20, 100, 0); });

For those of you who are interested, here are

Here's what it looks like after you click it:

The iframe of the chat box:

<iframe width="380" height="280" src="http://adviza.stackexchange.com/chat/iframe?key=6tJMyqSoOUid&amp;token=Yok0qhJckSA0" id="adviza-iframe" frameborder="0" style="left: 0px; position: relative; "></iframe>

Here's my little chat with the "expert".

    Yes, always click on random unexpected links in pop-up messages on websites where you don't expect. What harm can come from that?

    @JerryDodge: ...actually that was kept in mind. It was only shown to people for whom it was April 1 (I have seen the code, it checks the javascript Date()) Apr 19, 2013 at 3:38

It appears to be a mechanism to confuse newbies and make them feel unwelcome.

It is an April fools bot of course....

"Expert: Hello, how can I help you today?

User: Proof that you are a human and not an April Fools bot.

Expert: Oh right, it's April 1st today. I'll have to quit the internet for today. I don't have any humor.

User: Do you think you can pass a CAPTCHA?

Expert: Yes.

User: To prove that you're a human and not an April Fools bot... The only thing you need to do is to type the letters on this image: http://bit.ly/9BO2hm

Expert: Is it April already? Still feels like December.

User: So, please type the correct letters and proof that you're not an April Fools bot.

Expert: Is it April already? Still feels like December.

User: I'm sorry. You failed the test!

Expert: You're not the only one who is sorry."

It's a slightly freaky April Fools joke. I picked up on my third response that it's just a funny trick. If you ask the right questions you can actually have a conversation with the 'expert', must be quite an interesting algorithm. It 'breaks' when you mention April Fools a few times though


Direct answer to the original question: an annoyance… since I prolly have to click "never" on each and every SE site.

[Hint: stack exchange people should feel free to regard this as user feedback. ;) ]

This is an another unfunny joke from stuckoverflaw devs dedicated to 1st April day. "Expert" on the other side is merely a kind of ELIZA software easily recognizable by rephrased replies (that is, this software rephrases your message to form apparently sensible reply). The other kind of replies this software can give is indefinite (see the transcripts in the other answers).

My solution is to use AdBlock Plus:


because it wasn't humorous at all (I recognized a bot in 1 message by typing very fast and by "rephrased" pattern). Another annoyance factor was a failure to be unobtrusive - this element fails to be at the screen edge and obscures real page content.

I completely second @Dukeling's opinion on that: low rank on humour, high rank on irritation.

  • I thought I had gone some obscure adware at first but then realized the chat logs linked to this site. It is slightly funny, but it does get in the way. Apr 1, 2013 at 4:13

    Why adblock plus ? There is an option called Never on right side of the chat box,perhaps that should stop the caht box appearing on all pages.

I was fooled for some little while. I couldn't find the "transcript available online". But I had already copied.

@balpha to the rescue! http://adviza.stackexchange.com/transcript/9u1BXUJcs0HF

And then I was 100%.

Edit: this was highly unlikely to work:

Using code inspired from here, I'm trying to recover the link. I think it's an amusing one. But I'd like to take up a little less space here. :)

while true;
do u=http://adviza.stackexchange.com/transcript/$(tr -dc a-zA-Z</dev/urandom|head -c12);
curl $u -s 2>&1|\
