Is it because the email has been accessed several times within a short period from different ips? Surely, an option to try would be to delay the changing of the account by something like 14 days. For example:
- Seller gives credentials to swapd
- Swapd changes credentials 7/14 days later
- Swapd gives credentials 14 days later
- Buyer logs in
Yes, its not ideal if this is a workaround, and is a lengthy process, but surely this is a better alternative than offering no protection via a middleman service such as yourself. Swapd is all about quality, and for me I wouldn’t mind waiting a month for a property to be exchanged if the property was of a particular quality. Quick flips with Gmail are dead, but I’m almost certain that a lengthy process would alleviate their automatic systems flagging the account.
Although, I would agree. Swapd has expressed difficulties previously regarding ProtonMail: PSA: Stop using Gmail for your new projects, not worth the trouble if you're planning to sell your asset later - #17 by SWAPD
Yes, and no. You can factor this into your price, but this is additional cost. However, the major concern is that a lot of users buying the account will not want to pay a yearly fee to keep the domain running just for a email serrvice. So, although its a great idea it does limit you to certain buyers. Although, high quality accounts shoud be worth more than a few dollars every year to keep running.
