When we push a lead to Salesforce and convert it to contact, we automatically associate that contact to a 'Marketo Bucket Account' if there is no match. The second time when we create a new lead on the same email address (in our case if geography is different), and push to Salesforce, the Company Name on 2nd lead is 'Marketo Bucket Account' for some reason. This is despite having Account Name blocked from Marketo. The activity on the lead says 'Changed Conv Account from null to 'Marketo Bucket Account'. How can I stop this?
