In certain embodiments, the system 100 includes a plurality of feature adjustment modules 104 disposed/located on devices 102 of a plurality of different users (e.g., comprising hardware of and/or executable code running on one or more devices 102). The plurality of feature adjustment modules 104 may act as a distributed and/or decentralized system 100, executing across multiple devices 102, which are geographically dispersed and using different IP addresses, each downloading and/or aggregating data (e.g., photos, social media posts, medical records, financial transaction records, other financial data, and/or other user data) separately, in a distributed and/or decentralized manner. While a third-party service provider 108 (e.g., a financial institution, bank, credit union, and/or other online banking provider; a social media site; a medical provider; a photo hosting site; or the like) may block a data aggregation service or other entity from accessing data for a plurality of users from a single location (e.g., a single IP address, a single block of IP addresses, or the like), a distributed and/or decentralized swarm of many feature adjustment modules 104, in certain embodiments, may be much more difficult for a third-party service provider 108 to block.
