First I would look at my own social media browsing experience and look for any up and coming social media creators. The second method I would use would be talking with friends and family about what type of content and content creators appear on their feed, this is a way to get a lot more generalized data than simply my own social media preferences. I can also look through my own followers to see who they are following and if there are any trends. Finally, I would look through hashtags of key words related to the genre of creator I was trying to find. For instance, in the sports card hobby sealed boxed with packs inside are known as "wax" so by looking through the hashtag for #wax or #ripwax you can find specifically sports card creators.
