@MNHQ people are really just fed up now of "The Greatest Hits of MNHQ". 
If it's not "Send us a screenshot" it's "Tell us your browser and device". Neither of which seems to result in any action whatsoever. 
Not to mention the latest hit single titled "We're looking into it..." (which seems to go on for days and weeks. I mean, you're the host website and you've had more than enough info - how hard can it be MNHQ ?
(Family member works in IT - says it shouldn't be this hard for you to fix... unless you don't want to...?)
Anyway, I'm a long-standing user of adblockers and nothing I'm reading about on mumsnet is convincing me to change that. And, sadly, I suspect there are now many more mumsnet pp now thinking any adblockers are better than MNHQ's lack of action on intrusive and non-turn-offable ads these last few weeks.
And I'm really pissed off that Jersey has been tainted by this issue. There's no way Jersey tourism would want this negative experience by people being 'forced' to read its ads. And yet that's what's happening.
@MNHQ stop running ads for Jersey until you've sorted out this awful intrusive ad issue. You're really hurting our island with negative vibes when we need to recover after Covid.
