2. Keep a 4/5 second duration between every spam.

Then it's not spam.

If you don't want to get timed out.. Simply.. Don't spam, but If you really want to spam you can try to either:

1. Put a different letter-number-symbol in your sentence each time.

2. Keep a 4/5 second duration between every spam.

Never noticed

that doesnt work any more

Just refresh your page when you're timed out.

Leave this place, Dibbun.
