I'll have a cursory glance through the most recent memes made with any template I choose. I try hard not to repost, make memes from old jokes, beg for points or just make memes that aren't about things I don't actually think are meme worthy.
And even if you do purposely copy a meme, that still doesn't necessarily always make it a repost. You could have a different purpose or intention than the original meme, and put it in a different context.
