Oh really? 

Can't blank my user page, huh? Then why does WP policy state However, reverting such removals or redirects is not proper and may result in a block for edit warring.?

There is nothing of significant importance that I've removed from my user talk page, and I've been following WP rules strictly. By giving me a warning that is completely unwarranted as I've stated above, you're being hostile and I will give you a warning again if you attack me without contacting me for details of whatever I may have done, as that's uncivil. I'll remove your warning and not give you one this time  but read up on WP policy and discuss what's on your mind before jumping to conclusions and placing unwarranted warnings.
