Caches I ignore

Yesterday's geocaching forum post:
At what point do you start using the Ignore feature? 

Geocaching.com has an ignore list feature which allows you to ignore caches so that they do not appear in your search results. I think I started ignoring caches around year 7 of caching. With the exponential growth of caching and so many caches to sort through it's easier to remove the caches that I don't want to do from my pocket query and from my map. So what kinds of caches do I put on my ignore list? The forum topic's responses got me nodding in agreement with just about everyone's reasons for ignoring a cache. Here are some of those reasons:

• Puzzles that I don't understand
• Micro container puzzle caches
• Newly published micro caches where the write-up suggests they were planted just-for-the-numbers
• Needle in the haystack caches.. i.e. a cache under 100000 rocks
• Caches that I had no fun trying to find, gave up on them and don't want to go back to
• Caches that have unfavourable comments
• High Difficulty/Terrain caches especially the kind that require special equipment or risk life and limb e.g. tree climbing, cliff climbing
• Lamp Post micro caches in parking lots
• Challenge caches
• Series caches where you need to pick up numbers from micro caches to get the final coordinates to the last box in the series. 
• Back of shopping centers
• Kayak/canoe/boat caches
• Power trail micro caches 
• Most unknown size caches, people who hide nanos usually choose "unknown" instead of micro

Have I missed anything? What types of caches are on your ignore list?
