In the last month, I have identified a number of old accounts that have suddenly appeared as spammers. One today was from 2020, and it was removed/banned.
If you have a "simple password", or one that you use on multiple accounts around the web, I suggest you re-assess your usage, to avoid finding yourself banned here.
For most of you, not being able to post here may not be a "big deal", but, what if every site you shared a user ID and password on started showing you up as a spammer? Anywhere you are active should have a unique password.
