I would Check the SimilarWorlds Account Standing.

You reached the limit of X you can Y for now. Please try again later.
On SimilarWorlds, there can be times you receive errors like the following:

You reached the limit of friends you can add for now. Please try again later.
You reached the limit of times you may edit posts for now. Please try again later.
You reached the limit of messages you can send for now. Please try again later.
You reached the limit of comments you can send for now. Please try again later.
You reached the limit of photos you may upload for now. Please try again later.


When you get those errors, you just need to wait up to a few hours. Sometimes you only need to wait a few seconds.

Once the limit time has passed, you will be able to proceed.


Please note that these limits are necessary to prevent abusive usage, spam and bots on SimilarWorlds.

For example, if someone is adding several friends in just a few minutes, this can be considered irregular usage, and the user will be limited for some time.
The same applies for sending several comments in a row, hearting posts, editing settings, and many other things.

Another example is when someone creates a bot to spam their website or product, on SimilarWorlds, by sending messages to everyone.

Limits can go up and down depending on your profile's reputation. Once you continue to be a good member on SimilarWorlds, your limits will be increased and you will have more freedom.
