with tumblr suppressing the palestine tag and pushing pro-zionist propaganda through their ads, the least people here can do is disable their checkmarks/badges and stop buying more
can't speak to the tags thing but tumblr is definitely not pushing pro-zionist propaganda via ads because that's just not how ads work. ad space is bought and sold through a series of automated auctions that occur in less than a fraction of a second (highest bidder wins), which means nasty shit has a way of slipping through undetected—so if you see ads promoting hate speech or violence, these advertisers are violating tumblr's terms of service and you should absolutely report their asses to get them taken down and banned for good
I've seen at least one response to this along the lines of "okay it's still tumblr's fault for not screening ads though" and unfortunately that is ALSO not how ads work lol. when ads are bought and sold in real-time auctions, it's up to the advertisers (and the marketplaces who work with advertisers) to tag the ad according to one of several IAB content categories and subcategories—for example, IAB9-25 - Roleplaying Games.
publishers like tumblr can and do select what types of ads are displayed on their website based on these categories. for example, a website that hosts math games for kids might block the subcategory IAB7-11 - Cancer because it's not appropriate for their audience, and a website for music lovers might prioritize the subcategory IAB9-16 - Guitar / Keyboard / Drums because it is, in fact, extremely appropriate for their audience.
there are also two specific categories for "non-standard content" (IAB25) and "illegal content" (IAB26). most websites will rightfully choose to block ads tagged with IAB25-2 - Extreme Graphic / Explicit Violence.
but the problem here is that advertisers are the ones tagging their own ads! so if I'm a malicious advertiser, I'm either going to lie and tag my violent ad as something innocuous like IAB17-27 - Ice Hockey, or I won't tag my ad at all.
publishers (and the marketplaces who work with publishers) do not like when this happens and will often sever ties with the parties involved... if they find out about it. unfortunately ad analytics is a nightmare industry, and that's just measuring ads after the fact; trying to crack down on bad ads before they slip through is very difficult, especially since a single ad space can change hands three, five, seven times between the time it's auctioned off and the time it's sold and an ad is displayed.
which is why you should report harmful ads! not only will they (eventually) get taken down, but the advertiser behind them may also get banned from the platforms they do business with... at least until they try to change their tactics and operate under a new identity, or until another bad actor springs up to take their place. it's a constant struggle
