Yes, the addon was outdated. That's what causing the glitch, probably. It won't show without the extension enabled. I have tested several time. It only appears when the extensions are on. And only for one or two seconds.
For the sake of testing and investigation, I had to add this extension and test it myself, and I was able to reproduce it
First of all, yes, there's a post with a hero rank with this weird big number text, but it's hidden. You can still inspect the element and check the second post on the page with the class name "dummyPost."
This class with the display property: none means it will disappear as soon as the page is loaded.
This has nothing to do with slow speed or connection issues; it will always appear and disappear as soon as the page is loaded (if this extension is enabled, otherwise will be hidden by default).
Now, the question is, where is it coming from?No, it's not the extension that is adding this weird post; actually, this extension is doing a favor by showing and then hiding it after the page is loaded.
It's theymos... I mean, maybe, but yes, this dummy post exists on almost every page (check for yourself, inspect the tags around the ad)... not only one but three times... irrespective of if you are using the extension of not.
Only theymos can answer this, but I think it has something to do with the "ad", this bitcointalk ad that appears on every page after the first posts. Because I see there's a pattern, although the number will change as the ad changes, but the ID of this ad has something to do with these posts and this number.
Also, sometimes this post appears once, sometimes twice, or maybe three or four times in a row. It can be above the ad, or sometimes it's around the ad.
This is the code for the one of the posts if you can't inspect:

I have tested it in Chrome, FireFox and Edge same behavior, also it doesn't matter if you are logged in or not.
P.S. fahbil's
mobile extension named it 'dummyPost', so shoutout to fahbil.
It could definitely be the result of that Bitcointalk app and addon that he is using that is causing it.
No, this extension or app is not the reason for these weird posts, see above.
