:Hi Jac16999, thank you for your message ). This is not the first time i have tagged user pages of blocked users with blocked and other similar notices. I have been reverting vandalism, reporting vandals, and tagging them accordingly for many months now. I do it just for everyone's information that the said user has been blocked indefinitely, which can be changed or removed if the user's block has been changed or when the user has been unblocked. I did not find any policy or guideline regarding this, so just doing what i considered to be the right thing. If i have made any mistake or error regarding this or any other issue please do feel free me to point it out, i am always happy to correct any mistakes and learn from other users, and grow positively to help improve the project. Thank you.
