Complaint by Shad :

My primary source of traffic comes from publishing my blog posts. My audience is both women and men. I post early in the morning, the thought being to capture those people who read early and then throughout the day and evening. I can’t republish a blog post more than once a day. What I hear you saying is to publish micro-posts to social media networks at strategic times during the day with a link to my post. Do you advise posting via Buffer 2-3 times a day and Buffer will then post at the optimum times for each social network? http://allin1panel.com/blog/new-fuss-social-media-marketing/

Complaint by Brendon :

Thanks for sharing your experience ! I actually don’t have a team of graphic designers ans web dev to work with me full time so things take a little more time…also, the issue I’ve been struggling with is that I work in a small company. As a consequence, social media are not top priority and my superior tend to ask me to do other type of day to day missions( not necessarily related to communication by the way). http://allin1panel.com/blog/social-media-marketing-dead-alive/

Please help us keep Internet safer and cleaner by leaving a descriptive comment about 38.100.21.78 IP address


DNSBL* - is a list of IP addresses published through the Internet Domain Name Service (DNS) either as a zone file that can be used by DNS server software, or as a live DNS zone that can be queried in real-time. DNSBLs are most often used to publish the addresses of computers or networks linked to spamming; most mail server software can be configured to reject or flag messages which have been sent from a site listed on one or more such lists.

WHOIS** - is a query/response protocol that is widely used for querying databases in order to determine the registrant or assignee of Internet resources, such as a domain name, an IP address block, or an autonomous system number. WHOIS lookups were traditionally performed with a command line interface application, and network administrators predominantly still use this method, but many simplified web-based tools exist. WHOIS services are typically communicated using the Transmission Control Protocol (TCP). Servers listen to requests on the well-known port number 43.

** Approximate Geographic Location - This is NOT the exact geographical location of the person/organization with the given IP address. However, this should still give you a good idea about the area/region where this person/orgranization is located.
