Probably because most of these topics were scams. With some trying to make a profit at the cost of other people's disgrace. Now, I don't know if it's strictly forbidden on the forum, but it's something that should be done very carefully.
That was not a scam post. We are already very sensitive about those scam posts. Instead of collecting donations individually, I waited trusted NGOs to accept crypto donations. After long talks, we got the permission from the authorities and shared those crypto addresses from the original source.
Based on how some past aid efforts on the forum turned out, it is smarter to send all help straight to trusted non-profit groups like the Red Cross and Red Crescent working in Turkey and Syria. I am not a fan of those big and sluggish NGOs and I would rather give directly to those in need, but even that is far better than falling for scams who will use this bad situation for their own gain.
Unfortunately trust in government organizations here is much less than NGOs we mentioned. Also, they didn't have the option to donate with crypto. You can donate blood to Red Crescent though.
irfan_pak10 had donation thread some time ago when Pakistan was hit by flood or natural disaster. He got quite lot of enthusiasm from forum users who wanted to donate little money to the Pakistani people affected by the disaster. The thread is still available and not deleted until recently.
Those threads are very similar. I don't understand why there is a different approach to that thread. Anyway, the thread is restored second time. Thank you theymos.
