HOW TO BLOCK TAGS - Tumblr Posts
I'm not answering publically because I have zero desire to accidentially cause someone drama or backlash.
I do my best to tag as appropriate, but you may require a more robust system to avoid certain content or words, so you should use the safety tools provided on tumblr.
On the settings of your blog (desktop, not sure if this will show in the same place on mobile), you can marks words and phrases both in post tags or post content to be hidden from you.

The post will still show an entry (it will not be completely hidden), but you will need to acknowledge the warning about filtered content to view it. It is your responsibility whether or not you view filtered content. Shout out to purple for being an example.

You are responsible for curating your comfort level and exposure on the internet. Tagging, content warnings, trigger warnings etc are OPTIONAL features that many people on tumblr use to make it easier for others to curate their experiences, but they are not required.
Stay safe out there!
