Prevent this from happening
 

This is the first line of my post...
...and this is the second one...

and here you have the last one (which isn't the third)!

OK. Um, is there a question here?

Have no idea what this post is about. Looks more like spam

Well, this is how my first post looks: http://i50.tinypic.com/2duzep4.png
Do you notice the huge amount of space between lines 2 and 3?

The post should like like this: http://i45.tinypic.com/2eplshu.png

Maybe if you explain what you are talking about as this problem if any seems to be with u

Check post above yours.

Yes I seen that it still does not explain ur problem in other words you are not explaining how it happened. More info is needed? As I said above you are the only one with this problem so it could be a browser problem. Does it only happen on this site or all etc etc

I don't know... could you please post a screenshot of how my first post looks on your browser?

It's worth noting that I have intentionally pressed the "Enter" button of my keyboard a lot of times between lines 2 and 3 of my first post to make it to look like this because I want it to be parsed as this removing all those intentionally line breaks between lines 2 and 3.

Got it?

Wait a sec.... you hit enter several times in the post but you want the software to remove all the line breaks you entered? It doesn't do that. You need to only hit enter once if you want one line break.

Yes.

I know, that's why I'm asking here at vbulletin.org instead of vbulletin.com

I know.

I'm not the one doing this on my forums, okay? There are trolls who abuse of the 'Enter' key to generate a lot of line breaks to annoy other members.

Is there any easy way to alter the system so when it detects more than one line break then it simply 'compresses' all the line breaks to only one? As an example, when the system detects this, instead of displaying that it should display this.

I do not know of any easy way. You may want to look through the string functions for php here - http://www.php.net/manual/en/ref.strings.php - and see if one of those would work for you and then you can just write a plugin to run it on the page text prior to spitting it out.

Or.... how about banning these users? Or setting it up so the first couple of posts must be approved? Or putting them on global ignore?
