I got filtered two times, once, in r/veganrecipes for sharing images with a link in the body - after a period of regular, monotonous sharing. The same happened in c/cryptocurrency (when they filtered out a share of mine after it generated 10 upvotes or so) - i had been sharing for 2 months or so, precisely 3 times a week.
The conclusions: when they see a pattern of the bot, they start filtering.
But anyway I agree this filter thing is unpredictable.
So you say I try and share text or image rather than link share? It won't be valid for the contest but for normal rewards
I just described my experience of getting filtered. I didn't mean you should share through other types of posts.
But, yes, you can do it... I share both through link-type and image-type posts.
Yeah I mean to change the pattern
I guess it might help - just to dissolve your normal activity with other types of things. You can also create posts without links, like, ask something in r/AskReddit or join a discussion of a series you like - series often have a sub.
As they say:
I personally try to be active in different ways but get too tired with online.
