Is the "record of your seeking forgiveness" — which is presented in forums where members record their seeking forgiveness — considered the prohibited collective remembrance of Allah, or is it permissible?

The request to record Istighfar (seeking forgiveness from Allah) upon entering the forum is not considered a collective dhikr (remembrance of Allah) nor an added innovation (bid‘ah idafiyah). This is because there is no deliberate intention to gather for Istighfar at the same time, nor is there a belief in any special virtue for Istighfar at this particular moment. Rather, it is an utilization of the opportunity of gathering in the forum to remind those who enter and encourage them to perform Istighfar.
