they've done worse every time I used them: they jacked up the price well after my deposit was detected by them. I ended up losing several percents compared to the price they promised.

it's a scammy service and they invest a lot into event sponsorships (for conferences, meetups) to gain visibility. they also leave useless comments on GitHub issues, which also looks like self-promotion. just like this useless Lemmy post. I'll never use them again.
