The effect should indeed not be browser related, but rathermore search engine based, unless other installed browsers have some sort of Ad blocking features running.
Strangely enough, if I access the fake domain right now, what I get is the real original domain. They seem to have temporarily redirected the traffic to the real site, probably to switch it back to their fake content at will.
I stumbled upon a site to see if a given web is being redirected. Note that I haven’t used this site before, so I’ll enclose it here in code tags:
https://www.redirect-checker.org/index.php
When I parametrize it with the fake url into the above webpage, I get the following result:
Result
https[colon]//elekclrum[dot]org/#home
302 Found
https[colon]//electrum[dot]org/
200 OK
Problems found:
You use a 302 redirect. This means, that the actually content is temporary not reachable and will come back soon. To use a 302 redirection for generally moved pages is a bad idea. Search engine bot might not follow it or handle it as temporary. For SEO this is also a bad idea, because no link juice will be transferred to the linked page.
Note: I changed dots for [dot] and the colon for [colon] above.
