Apparently ads are not supposed to do that.
Maybe you can try to report that ad via the "x" button in the lower right corner of the ad, then you have a feedback button.
Or do that behaviour occur with all ads in mobile?

Strange, on the forum I get only annoying banners on left & right and at the bottom
Unfortunately I can't do much on the forum, I think these are automatic Google ads.
I'll mention it to the forum owner just in case, but I guess he'll reply me it is the automatic thing from Google...
Someday maybe I should migrate the forum to something hosted on IMCDb's servers, but that is probably not so easy (as many posts of the forum would be worth keeping).

edit: now that think about it, on mobile I don't have ads on the forum because I use Firefox with an ad blocker by default, as usually ads use way to much resources on many sites

The last couple of days I've got this banner that covers most of the screen. You have to press the up arrow to remove it but when you go to another section of the forum you get it again, and again, and again...
Highly annoying.
I use Chrome on an Android phone.

Hmm, it might be a useful feature, indeed...

I could trim the text, but it was actually kept on purpose: if you want to find all the Cutlass-something and not those with just the base name.
Maybe that behaviour should be kept only for the advanced search, though.

I just did a search for 1967-1967 Oldsmobile Cutlass convertible, I was surprised that it only returned Cutlass Supremes. I used the auto fill function on my phone which adds a space. This rendered a search with only Cutlass_ i.e. Cutlass Supremes without the Cutlasses.
Is it something that can be fixed or is it something just to be vary of?

I think I have been fooled by similar searches in the past...

AHHHH... now, I understand. I should've looked in here years ago.

For me, it's annoying, because I usually do this when I see that I made several comments in a row on one page in the span of a few years, or something like that. So I try deleting one to make the page less cluttered... but then, it stays there, saying "deleted comment". I get that that's not a problem for most people, but still...

The forum issue seems fixed

Problem seems fixed, I found the issue in page that Andyhao sent me

I had the same issue on the forum (in Firefox) so it is not browser-related, and unrelated to the title issue anyway. Maybe a temporary issue on the forum itself, which I don't manage anyway, if the issue continues in the next hours I'll notify the owner of the forum.
For the site however I'm curious on what causes that.
