OK now I see what you mean, it only showed up after I clicked through a result, and its just a banner at the top, I can scroll past it. There was no need to click the 'x' button.
edit: and now that I clicked 'x' it seems to not show again.
I think it is because I originally clicked, 'maybe later'. Which made the second pop-up nag thing come up, and maybe made it more interested in repeating the message, or something.
When I'm concentrating on something, and want to just immediately know the answer to something, and/or get more information. E.g. Perhaps I'm reading another webpage, extensively, and just wanted to know what they meant by something, etc.
I can get frustrated, when the other web-page(s), attempt to distract me with annoying pop-ups, adverts and other stuff.
When I'm less busy/occupied, I would have more time and energy, to consider their monetary requests, and spend time reading their stuff.
I'd much prefer them to just have a small/tiny banner/section/bit in the top right hand corner, called something like
Donations/Funding-Help, rather than (annoying to at least me), pop-ups, which have to be clicked in certain ways to cancel/remove.
Don't get me started on these annoying EU regulated, we have cookies, jamming up many web-pages these days. Until you go through their (sometimes multi-pages and complicated), cookie details things, disable each section, one by one. Then have to find the accept/save options button. To unfreeze and then read the webpage.
We (UK) are not even in the EU now, and it could have been done in a much more user friendly manner. NOT semi-breaking the internet, kind of way.
