I have been warned for approaching the limit for a feature.

Gnommie has determined that you were using a feature at a
rate that is likely to be abusive. For example, you may have been warned about approaching the limit for posting comments based on how many comments you posted and how fast you posted them. This is just one of many features Gnommie has in place to help stop abuse. Don’t take it personally, but instead, take a deep breath, grab yourself a cup of coffee/tea, and come back and join the conversation again. These blocks can last anywhere from a few hours to a few days. Unfortunately, we cannot lift the block for you.

In the future, be cautious to avoid hitting the limits again, as further abuse of such features can result in your account being permanently disabled.
