On every platform that i create an account on, i use a new randomized email address. This allows me to track which platforms sell my account info to spammers.

The one i used for now receives astonishing amounts of spam (mostly bitcoin spam atm).

I hope you don't sell the account information of your contributors to third parties, but instead believe in a design flaw of your bug tracking system and some way that spammers can currently harvest the email addresses of all of your contributors.

Please investigate how this is possible and ways to protect your user's data.

oh, how convenient... as a logged in user i can just see every other user's email... but there's more, I can just go to and see all "obfuscated" emails. A low hanging fruits approach very likely will return most of the real emails:
'.'.join(s.split()[:-1]) + '@' + s.split()[-1] + '.com'

Let me provide you with a preliminary free analysis of the 50 most frequent email domains of all 21803 users on

10554, "gmail"
3663, "sourceforge"
411, "yahoo"
179, "googlemail"
176, "co"  # low hanging fruits as i said
167, "gmx"
98, "hotmail"
92, "com"  # low hanging fruits as i said
81, "google"
69, "163"
62, "redhat"
57, "mail"
51, "ac"
51, "me"
50, "web"
43, "free"
41, "mit"
41, "qq"
40, "org"
33, "iki"
30, "yandex"
28, "python"
25, "comcast"
25, "edu"
25, "pobox"
23, "id"
22, "ibm"
21, "acm"
21, "fastmail"
20, "live"
19, "mac"
18, "mailinator"
18, "net"
17, "126"

16, "protonmail"

Please make this a bit harder!

We don't sell any information to anyone. If you would like to file a bug to have email addresses obfuscated more then the correct place to file that is .

Obviously any help in updating the code would be appreciated as the issue tracker predates e.g. bitcoin and this is entirely volunteer-run.
