fix #2242

[ntexe]

Fixed #2242. I added regex check to three sites that caused an error.

There's a limit of 63 for label values, so i used {1,63} in regexCheck. However, smugmug clips username at 35 characters, so i used {1,35} in regexCheck.

The regexCheck seems to allow only one character for the username, which is incorrect. It should likely allow multiple characters. To correct it

{
"errorType": "response_url",
"errorUrl": "https://booth.pm/",
"regexCheck": "^[a-zA-Z0-9@_-]$",
"url": "https://{}.booth.pm/",
"urlMain": "https://booth.pm/",
"username_claimed": "blue"
}
