Need some help - Tier 1's get removed.

Hey guys, I'm having trouble with my articles staying on wiki sites. Here's what I have been doing...
I write around 550-600 words based on a video game as a review. Once I'm done I start sentence spinning by adding 2 different sentences. Once that's all done I go into word spinning. I do this by hand and make sure every word makes sense. I make sure that once its spun it is 100% readable. Then I paragraph spin it to add some more uniqueness just in case. Once that's all done I post it to wiki sites.I get around 56% uniqueness for my articles. I usually end up with around 300 links. However, the next day I do another link check before I bookmark them to pligg sites (tier 2) and I wind up with around 80 wiki links. So when I start backlinking my wikis some of them are dead. I'm wondering how I can overcome this? My articles arn't at all spammy and are totally readable. Even my titles are spun to a large variation. The only thing that I can think of is my anchor texts are spamy. An example of my anchors would be like "Free Amazon Codes" (example: Not my actual niche.) Maybe I'm doing something wrong? Or is constantly harvesting and posting to new wiki sites a part of the game?

From what I understand with Wiki links I would suggest cleaning up your anchor text a bit.
Hand written articles always do better than anything spun, but as you know it takes a lot more time or labor cost.

wiki sites die very fast.. try making web 2.0....

use wiki for tier 2 or 3 , or split tier 1 between web 2.0 , guest posts and wikis etc.
And if you are submitting to same wikis several times , I suggest changing you ip also.

wiki's are always gonna die quickly, they are almost useless for tier 1 imo and look pretty spammy.
