I think that you should be fine unless you did explicitly illegal things in the past. Ideally your vendor account on SR will have no link to anything you did online in the past, and the only way past online behavior will compromise you is if it in itself is enough to get you put under investigation. For every SR vendor who googled for drugs or downloaded drug related .pdf files from torrent sites, there are thousands of small time drug users and even non-users just curious about drugs who did the same thing.
