o_e_l_e_o was last active on 22 January. In his farewell thread, he mentioned that the account would soon be banned after he is done with his final goodbyes. BPIP doesn't show such accounts (locked) as banned. That's also the case with Lauda and satoshi. I just checked the modlog and there is no information there either. Anyone knows if the account has been locked/banned already?
Although, I don't really know either that account of o_e_l_e_o is banned or locked but I'm sure that no one will be able to use that account from now on because he left the forum himself and shared something that we all understand is a final goodbye to the family.
When Lauda left the forum no one yet used that account after that and similarly the o_e_l_e_o's account won't be used by anyone because he willingly left the forum for a genuine reason and that's why he left his farewall message for us.
I think an admin or a global moderator might be able to shade some light that what happens with such accounts when owners willingly share farewell messages and say that they won't be using the forum anymore.
