We have limits in place to reduce downtime and errors. These limits help prevent spam and other attacks, as well as help maximize site performance for our users. We've set the limits pretty high so you may never see them at all.
The limit for following other users is currently set to 5000 users. Following more users than that causes a heavy load on our servers when loading your dashboard and can make the site slower for everyone. You may want to review the list of users you are following and remove any that are inactive, so you can find new users to follow for inspiration!
This limit is currently set at 200 hearts per hour. If you're constantly reaching this limit, we're glad you’re enjoying We Heart It. Hearting more images than that in that period of time causes a heavy load on our servers and can make the site slower for everyone.
When you reach the limit you'll see a warning message and you won't be able to heart until after an hour has elapsed. We recommend you take a short break and check back soon to be able to heart more -- or get creative adding your existing hearts to collections!
