I click save password during registration of my account but I have an account I did same but unfortunately couldn't render successful because the VPN is associated to crime related activities and I still have such an account exist but useless. How can I remove those account that existed but useless because it can't reply or quote in any topic. Please I need your contributions.

I think each case should be viewed differently.
As we know from the history of this forum, most banned members have failed through such topics to get forgiveness from the admin and a second chance at this forum.
However, in very rare cases, some banned members with the great support of the forum community managed to get forgiveness from the admin and their permaban was removed, based on their contribution and importance to the forum.
Based on that, I don't think moderators should be asked to remove such threads.
If a topic has the support of the forum community then it will survive and stay active for years, if needed.
Otherwise, if there is no support from the forum community, the topic will die naturally and there will be no need for any moderator intervention.

Please close registration or do something against this fucking phishing bots. Its a pain that this forum do nothing against this shit!!!!!!!!!

Make rules that new person can´t post links, delete old not used accounts, and so on. But to do nothing and only delete such posts after several hours helps no one!
