"If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness." 1 John 1:9

Online confessions are blasphemy. Why?, because your confessions are meant for God. Your confessions are for God's ears only. Stop confessing online, if you’re truly honest you will see that you’re doing it to glorify your sins. If you don't believe in God then why are you confessing? Is it to unburden yourself of your dark secrets? I can assure you that it won’t work. If you confess without a repented heart then your confession is worthless. Don’t confess your sins to people you don’t know. Confessing to the internet will not bring about a change of heart or cause you to repent, it may even have an adverse effect. Confession with a trusted friend or loved can help. Ultimately take your confessions to God and he will forgive you. If you are suffering and need help please contact one of the following resources.

What is implied in "confessing our sins?" It must mean something more than merely verbal confession. "God abhors the sacrifice, where not the heart is found."

Confession implies that we understand what our sin consists in. And that we repent from those actions daily. A true confession implies that we cease from all known sin, of either omission, or commission. Also, that we cease from all excuses or apologies for sin. He who makes an honest confession does it under the heart-conviction that all sin is utterly wrong. Feeling this, he cannot say one word in excuse or apology for sinning.

5 Then I acknowledged my sin to you
and did not cover up my iniquity.
I said, "I will confess
my transgressions to the LORD "—
and you forgave
the guilt of my sin.
