Image upload is such a hassle on DNM and I already started using the product. I'm a genuine buyer and I can confirm in DMs through other methods if you want.
Seems like an OpSec hazard to me. I just checked that dump.li doesn't remove EXIF data from images. I wouldn't want my device model or other sensitive data to be revealed to public. Some phones have location enabled in their camera settings so coordinates are always added in EXIF data and dump.li doesn't remove any of that.
I haven't done proper research on it yet but you could turn the crystals into fine powder and then dissolve it into distilled water. Put about 150mg/1ml and then store it in a nasal spray bottle. Some people add a bit of salt and alcohol for various reasons. Do your own research before trying this.
