does my account have loot drop penalty ?

hi i am spamming normal eater of world all of them rare and corrupted , from what i know the odds are between 5 to 10% chance to get a forbidden flesh from each invitation .
but in the past 80 invitations i have yet to see one , lets say my roles give me the average of 7% chance to drop one , the odds of not getting a single one after 80 invitations is 0.3% , so it is abysmally insane to not even see one .

so I ask again is my account having a drop rate penalty ?
if so plz do tell me thanks

(ps it might be more than 80 i have not seen one drop in such a long time i don't even remember )
