If you're not able to follow any more Behance members, you've likely hit a follow limit. Behance has imposed following limits to prevent abuse and avoid system strain.
If you've hit a limit, you'll see an error whenever you try to follow someone.
Behance's technical follow limits:
Account-based follow limits: All accounts can follow up to 2500 members. Based on your ratio of followers to following, you may be able to follow more people than that. If you hit this limit you'll need to unfollow enough accounts you're currently following to be below the overall limit. Follow limits are system-wide; Support cannot remove or adjust your follow limits.
Time-based follow limits: To discourage spammers, we've imposed limits for the number of people you can follow or unfollow in a certain time period. To build up your activity feed, we recommend following a selection of people whose work you like, but following an excessive number of people is against our community guidelines. If you see this message, you'll be able to start following/unfollowing people again within one day.
What to do if you've hit a follow limit:
If you've reached the account-based follow limit, you'll need to unfollow enough accounts you're currently following to be below the overall limit. Follow limits are system-wide; Support cannot remove or adjust your follow limits.
Why we limit following behavior:
Limiting the number of follows helps keep your activity feed and notifications full of fresh work you're interested in and encourage high quality connections on Behance. Limits also keep our site performing quickly and reliably. Automated or scripted following is considered abuse on Behance and violates our Community Guidelines. For more about this, read our Community Guidelines section on automated or scripted behavior.
